Application of Geometry in Daily Life

Geometry is most widely used application based mathematical concept used in our daily life. 
This is a part of applied Mathematics and is used extensively from construction to space research. 
Geometry was evolved in 300 BC by Euclid known also as the father of Geometry, a Greek mathematician, was not meant only for mathematical concepts but for many normal applications for any person who has basic understanding of the concept. 

It is considered as one of the oldest concept and is concerned with shapes and sizes of the relative figures and with properties of space. 
Application of geometry in daily life consists of more than thousands of applications varying from lowest level to the highest end.    

Let us consider some cases such as while constructing a house it is very important to Pre-Calculate the dimensions all the rooms, parking space and other utilitarian. 
How much should be the parking space, how much should be the balcony width and length, and how long should be the supporting pillars, all these several questions can be answered just by one single concept that is geometry.
Any physical space could be calculated by using the Geometrical concept. The entire Geometry is divided into two parts: one is plane Geometry and while the other is solid Geometry. 
Among the personalities, architects are one of the most extensive users of geometry.  
Defense applications are again one of the best examples of application of geometry in daily life. 
Daily operations of military consists much of real life Geometrical application such as loading of arms and piling of ammunition and firing of missiles. 
Locating the coordinates and then launching the missiles is another example of application of Geometry. 
At home based applications such as finding the square footage at the home for placing a refrigerator or locating a space to fit in an air conditioner requires calculation of the space required and this done by using area and volume concept. 

While whitewashing we need to make an estimate how much paint is required for the walls and roof, and without geometrical calculations it would be nearly impossible for us to calculate the amount of paint required. 
While cooking, the size and shape of pan or container matters a lot. 
One cannot cook 10 peoples food in a small pan, and hence we need to estimate the size of the container and the pan once we know how many peoples food needs to be prepared. 

Another very interesting application of geometry in daily life is the use of it in computer graphics. 
Bio technology and Medical science also use geometric concepts too much for their daily operations.
Large real estate developers use geometry in all their operations right from planning till deploying the plan. 
The entire facility planning and layout of the project and scheme needs more of attention to suit the people, such as how to plan that a 40 storey building having 4 flats per floor, has at least one balcony in each flat. 

This requires huge amount of planning and research on the layout of the project, which is again based on the Geometrical concepts. 
In any production and assembly line of an Industrial unit, there are important decision to make based on certain deduction, such as how long should be the assembly line, how much space and the surrounding location should be provided for a machinery to work proper. 

Designing a production and facility layout of a plant requires an expert who is have deep knowledge of geometry and has implemented his/her plans earlier to any plant design. 
One of the most technologically used application that uses geometry is the evolution of 3-D, which is a step forward for an effective usage of technology.

Figure drawing

Figure drawing is an exercise in drawing the human body in its various shapes and positions. "Life drawing" is the process of drawing the human figure from observation of a live model. Figure drawing is arguably the most difficult subject an artist commonly encounters, and entire classes are dedicated to the subject.

The human figure is one of the most enduring themes in the visual arts, and figure drawing can be applied to portraiture, cartooning and comic book illustration, sculpture, medical illustration, and other fields that use depictions of the human form. Figure drawing can be done very simply, as in gesture drawing, or in greater detail, using charcoal, pencil or other drawing tools. If pigment is used, the process may be called figure painting.


Artists take a variety of approaches to drawing the human figure. They may draw from live models, from photographs or other reference material, from skeletal models, or from memory and imagination. Most instruction focuses on the use of models in "life drawing" courses. The use of photographic reference—although common since the development of photography—is often criticized or discouraged for its tendency to produce "flat" images that fail to capture the dynamic aspects of the subject. Drawing from imagination is often lauded for the expressiveness it encourages, and criticized for the inaccuracies introduced by the artist's lack of knowledge or limited memory in visualizing the human figure; the experience of the artist with other methods has a large influence on the effectiveness of this approach.

In developing the image, some artists focus on the shapes created by the interplay of light and dark values on the surfaces of the body. Others take an anatomical approach, beginning by approximating the internal skeleton of the figure, overlaying the internal organs and musculature, and covering those shapes with the skin, and finally (if applicable) clothing; study of human internal anatomy is usually involved in this technique. Another approach is to loosely construct the body out of geometric shapes, e.g., a sphere for the cranium, a cylinder for the torso, etc. then refine those shapes to more closely resemble the human form.

For those working without visual reference (or as a means of checking one's work), proportions commonly recommended in figure drawing are:

  • An average person is generally 7-and-a-half heads tall (including the head). This can be illustrated to students in the classroom using paper plates to visually demonstrate the length of their bodies.
  • An ideal figure, used for an impression of nobility or grace, is drawn at 8 heads tall.
  • A heroic figure used in the depiction of gods and superheroes is eight-and-a-half heads tall. Most of the additional length comes from a bigger chest and longer legs.

Note that these proportions are most useful for a standing model. Poses which introduce foreshortening of various body parts will cause them to differ.


The French Salon in the 19th century recommended the use of Conté crayons, which are sticks of wax, oil and pigment, combined with specially formulated paper. Erasure was not permitted; instead, the artist was expected to describe the figure in light strokes before making darker, more visible marks.

A popular modern technique is the use of a charcoal stick, prepared from special vines, and a rougher form of paper. The charcoal adheres loosely to the paper, allowing very easy erasure, but the final drawing can be preserved using a spray-on "fixative" to keep the charcoal from rubbing off. Harder compressed charcoal can produce a more deliberate and precise effect, and gradated tones can be produced by smudging with the fingers or with a cylindrical paper tool called a stump.

Graphite pencil is also commonly used for figure drawing. For this purpose artists' pencils are sold in various formulations, ranging from 9B (very soft) to 1B (medium soft), and from 1H (medium hard) to 9H (very hard). Like charcoal, it can be erased and manipulated using a stump.

Ink is another popular medium. The artist will often start with graphite pencil to sketch or outline the drawing, then the final line work is done with a pen or brush, with permanent ink. The ink may be diluted with water to produce gradations, a technique called ink wash. The pencil marks may be erased after the ink is applied, or left in place with the dark inks overpowering them.

Some artists draw directly in ink without the preparation of a pencil sketch, preferring the spontaneity of this approach despite the fact that it limits the ability to correct mistakes. Matisse is an artist known to have worked in this way.

A favored method of Watteau and other 17th and 18th century artists of the Baroque and Rococo era was to start with a colored ground of tone halfway between white and black, and to add shade in black and highlights in white, using pen and ink or "crayon".


The human figure has been the subject of drawings since prehistoric times. While the studio practices of the artists of antiquity are largely a matter of conjecture, that they often drew and modeled from nude models is suggested by the anatomical sophistication of their works. An anecdote related by Pliny describes how Zeuxis reviewed the young women of Agrigentum naked before selecting five whose features he would combine in order to paint an ideal image. The use of nude models in the medieval artist's workshop is implied in the writings of Cennino Cennini, and a manuscript of Villard de Honnecourt confirms that sketching from life was an established practice in the 13th century.

Question:me in class 10th and need to make a model on the application of 3d geometry in daily life...........please help....please..suggest some sites

Answers:3D geometry explains different object with three-dimensional shapes, that cannot be sketched on papers. Spheres, Cones are the example of 3D. A ball is used in daily life. Motor car tyres are cylindrical and are also in daily use. You look at your TV which is a 3D object of daily use. A die is in the shape of a cube. A portable DVD player is in the shape of a rectangular prism.

Question:TESTS: a. putting NaOH solution and nitric acid-PROTEINS b. putting iodine solution-STARCH c. rubbing fats on a paper-FATS

Answers:(A) Police forensics units use this one to 'develop' fingerprints in certain circumstances. (B) Outside of a general biology lab, I cannot imagine any practical use in daily life. A sort of reverse version has been used as a medical test for sweating. An iodine solution is applied to the skin and allowed to dry, then dusted with starch. Since the reaction requires water, the treated skin will turn purple-black if/when sweating occurs. (C) The pioneers and other non-technology peoples used to make translucent window coverings by rubbing fats into thin animal skins. This allowed them to keep out the cold winds while letting in some daylight. I suppose there might be some similar application for paper, but I can't think of one (aside from maybe using it as a fire starter; fat-soaked paper would burn pretty easily).

Answers:Clinical? Not sure about clinical....but in day to day life for Mining, to dissolves rock around gold, Vinegar, Bleaches, Agents such as bathroom mold removing products, Citric Acids used in cooking...the list is abundant!

Question:All those algebraic equations, are they relevant when our daily life is concerned?

Answers:It does teach you another way of looking at things. For example, if I wanted to make something which calls for 2 cups of sugar, and I only have 1 1/2 cups, how can I adjust the rest of the ingredients to I can still make the cookies? I don't have to use algebra for that--but can if I want.
