Question

On a piece of paper, sketch or use a protractor to construct right triangle ABC with AB=3 in., m∠A=90°, and m∠B=45°.

What statement is true about the triangle?

A. BC=3 in

B. AC=3 in.

C. AC=6 in.

D. BC=6 in

Answer 1

B. AC = 3 in.

because when there is a right triangle with an angle that equals 45 degrees, all sides, not including the hypotenuse, are automatically congruent. This triangle is like that. So if one side, that is not the hypotenuse, equals 3 then the other aide equals 3.
