In this proving triangles congruent worksheet, 10th graders solve 5 different problems that include proofs and proving congruence in triangles. First, they determine which postulate can be used to prove the triangles congruent and mark all congruent parts in each figure by completing the proof statement and identifying the postulate that proves their congruence. Then, students write each of two proofs.
