Answers:equilateral, isosceles, and scalene are terms that apply to the sides of triangles. Acute, right, and obtuse are terms that apply to one angle of a triangle, with the other two being necessarily acute. (All triangles have at least two acute angles.) An acute-angled triangle must have three acute angles, but the side lengths can be all different, so the answer is yes. (A right triangle has one right angle, and an obtuse triangle has one obtuse angle.)
Answers:No because you would need two angles over 90 and two numbers over 90 would automatically add up to more than 180 degrees. All three angles in a triangle must add up to no more or no less than 180 degrees.
Answers:An acute triangle and a trapezoid, and a rhombus too, but i have a question for you, how are you going to give 10 points to all the people who give u the names of 2 shapes!!!If you don't know save yourself all that trouble of figuring it out and give me the 10 points!!!
Answers:No, for both... Isoceles This cannot work because in an isoceles triangle, at least 2 sides have equal length, which results in at least 2 angles equaling each other. Therefor, you would have 2 angles equal to eachother, plus 1 other angle. So, you don't have enough angles to accomidate for all 3 you wanted. Scalene This one can't work because if you start off with a right angle, you have 90 of your 180 of angles accounted for. Then, move onto an obtuse angle, which has to be greater than 90 . So, right angle + obtuse angle > 180 , meaning the figure is not a triangle. Anyways, if you have a right angle in a triangle, it is a right triangle, it can't be called by anything else.
