Question:and what are some real life example of a congruent angle?
Answers:Congruent angles are angles with the exact amount of degrees for instance.. 2 angles that are 90 degrees are congruent angles. Another example is 2 angles that are exactly 23 degrees..these angles are congruent. Real life example: Most buildings stand 90 degrees with the ground.

Question:are tangent, what is the measure of the radius of one of them?
A 3
B 5
C 7
D 8
E 10
Explain your answer.
Answers:Think about it for a second. If the two circles are tangent to each other and are congurent, the radius must be half of the distance between their centers. Let's figure out this distance. [ (x_2  x_1)^2 + (y_2  y_1)^2 ] = { [6  (2)]^2 + (9  3)^2 ] = ( 8^2 + 6^2 ) = 100 = 10 Therefore, the radius would be 10/2 = 5 and the answer is B. Hope this helps!

Question:what about if all the sides of the triangles are congruent to another one, are the triangles congruent?
Answers:if all the corresponding angles of 2 triangles are congruent, then they are definitely similar triangles, not necessarily congruent, as an infinite number of triangles with the same angles exist. On the other hand, if 3 sides are congruent, then the 2 triangles are congruent.

Question:The word 'circle' is used in the Bible with respect to the earth and is thought to prove the earth is a sphere.
Isn't it false to say that if something is a circle it must necessarily be a sphere?
Isn't it more likely that the word 'circle' is just the same as it means in the Sumarian myth of the flat earth? THX1138  the first and best film of George Lucas.
Answers:Did they really differentiate that much back than? Did they have mathematics to the point of complex geometric shapes? Now its different but I don't know about back then. Did you name your avatar after some '70s Bmovie? I can't believe somebody else actually saw that movie.

Congruent Figures Part 2  Proving Triangles Congruent  Definition of Congruent Triangles :mrpilarski.wordpress.com The second part of this series about congruent figures is proving triangles congruent. At this point, there is only one way to prove triangles congruent, with the definition of congruent triangles. Congruent triangles have 3 pairs of corresponding angles and 3 pairs of congruent angles. So, to prove two triangles congruent, we must establish that all 3 pairs of corresponding sides and angles are congruent. The third angle theorem states, if two angles of one triangle are congruent to two angles of another triangle, the third angles are congruent to each other.
