Ineed some with a geometry question. is very much appreciated!

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.

Triangles A + B are not congruent to any others.

Hope this helps!! :)

If there's anything else that I can help you with, please let me know!

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

95.03 is the answer. hope this !
