Question

7 State if the two triangles are congruent or not congruent. If they are congruent, state the theorem (one of the five) that proves they are congruent. 1 Show Your Work

Answer 1

First we have to choose the theorem. It is going to be the SSS theorem. We can see both triangles share one side. Lines in red indicates there are two other sides that are equal. And finally, since it is a parallelogram the third side must be equal for both. With that information, the conditions of the theorem are complete and we can state these two triangles are congruent.
