Question

I need some help with a geometry question. Help is very much appreciated!

Answer 1

First off,congruent triangles are triangles that are equal to another,having the same area,length of sides and angles.

Judging visually,the triangles that are congruent would be:

C and E-as they are both in smaller size.
D and F-as they are both significantly irregular.

That would left A and B:

A-it is very large in size that none other could match
B-it is the only isosceles triangle.

Thus the answer is A and B as they do not match with any others.

Hope it helps!

Answer 2

Hey there!

Congruent means to be exactly the same. So for these triangles, let's go through each triangle.

Triangle A - There are no other triangles that are the same size, so it is not congruent to any other triangles.

Triangle B - There are no other isosceles triangles of the same size, so it is not congruent to any other triangles.

Triangle C - There is another triangle that appears to be equilateral, as is this one. So, it is congruent to another triangle. The triangle that is congruent to this one is triangle E.

Triangle D - There is another triangle that appears to be obtuse, as is this one. So, it is congruent to another triangle. The triangle that is congruent to this one is triangle F.

Triangle E - This triangle is congruent to triangle C.

Triangle F - This triangle is congruent to triangle D.

Answer: Triangles A + B are not congruent to any others.

Hope this helps!! :)
