Question

which theorem shows that △abc≅△def? the triangles are not congruent. isosceles triangle theorem sss triangle congruence theorem sas triangle congruence theorem

Explanation:

The tick - marks on the sides of the triangles indicate that the three sides of $\triangle ABC$ are equal in length to the three corresponding sides of $\triangle DEF$. The SSS (Side - Side - Side) Triangle Congruence Theorem states that if the three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

Answer:

C. SSS Triangle Congruence Theorem
