Question

1. which theorem will prove that the sides opposite the 70° angles are congruent? corollary to the converse of the isosceles triangle theorem converse of the isosceles triangle theorem isosceles triangle theorem corollary to isosceles triangle theorem

Explanation:

The Isosceles Triangle Theorem states that if two angles of a triangle are congruent, then the sides opposite those angles are congruent. Here, we have two 70 - degree angles, and we want to prove the sides opposite them are congruent. The theorem that directly applies is the Isosceles Triangle Theorem.

Answer:

Isosceles Triangle Theorem
