Question

PLEASE HELP THANKS 

On a piece of paper, use a protractor to construct right triangle ABC with AB=4 in. , m∠A=90° , and m∠B=45° .

What statement is true about the triangle?

BC=8 in.

AC=2 in.

BC=4 in.

AC=4 in.



EXPLAIN WHY

Answer 1

AC would be equivalent to 4. I know that the triangle is a 90, 45, 45 triangle which means 2 of the angles AND sides are equivalent to each other. Since angle B is 45 degrees angle C has to be 45 degrees. Same goes for the sides. Since AB=4, AC=4. It wouldn't be BC bc that's the hypotenuse or the longest part of the triangle. AC wouldn't be equal to 2 since it won't follow the rule of a 90, 45, 45 triangle. :|
