Atriangle has a 90° angle, and the other two interior angles are congruent. explain how to find the measure of one of the two congruent angles.

well  we already know that a triangle degree is 180 and we already have one degrees angle which is 90 so in order to figure it out we'll have to subtract them both:

180 - 90= 90

were left with 90 now we know that the other two angles are going to be some what equal to 90 and since the two angles are "congruent" meaning its going to be half. therefore, were going to divide it by half (2)

90/2 = 45

45 is your answer  :D
