Given that ∠A≅∠B , Evelia conjectured that ∠A and ∠B are acute angles.Which statement is a counterexample to Evelia's conjecture?m∠A=126° and m∠B=126°m∠A=30° and m∠B=40°m∠A=45° and m∠B=45°m∠A=114° and m∠B=170°

Question
Answer:
A counterexample is an example which disproves a proposition.

Given that Evelia conjectured that <A and <B are acute angles. Since, <A is congruent to <B, a counterexample to the conjecture is two equal angles which are not acute angles.

An acute angle is an angle smaller than a right angle (it is less than 90 degrees and more than 0 degrees).

Therefore, the statement that is a counterexample to Evelia's conjecture is m∠A=126° and m∠B=126°
