Question

Which of these triangles are definitely not congruent to any of the others?

Check all that apply. I think it’s c and d but I’m not sure!

Answer 1

Your correct, it's C and D

Explanation:

A and E are right triangles, so that's not the answer. B and F are isosceles triangles so that's not the answer. C and D are 2 DIFFERENT obtuse triangles so that's why C and D are the answers.
