Question

problem 6: complete this sentence with the best of the choices given. if two triangles are ____ to the same triangle, then they are ____ to each other. a b c d e congruent; not congruent

Explanation:

Step1: Recall congruence property

Congruence of triangles is transitive. If $\triangle ABC\cong\triangle DEF$ and $\triangle GHI\cong\triangle DEF$, then $\triangle ABC\cong\triangle GHI$. That is, if two triangles are congruent to a third - triangle, they are congruent to each other.

Answer:

If two triangles are congruent to the same triangle, then they are congruent to each other. So the correct choice is not provided in the given option "A. congruent; not congruent". The correct answer should be "congruent; congruent".
