Question

An Isosceles right triangle has a 90 degree angle and 2
equal acute angles. What is the measure of each of the
acute angles in this triangle?
A. 45 degrees.
B.144 degrees.
C.36 degrees.
D.108 degrees.

Answer 1

They are 45°.


Explanation:

A triangle equals 180° so if one of the sides is 90° and the other two are equal we know it has to be half of 90 because 90+90 is 180
