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°
