Find the measures of the acute angles of an isosceles right triangle.

45 degrees

Step-by-step explanation:

Since an isosceles triangle has two equal sides, it is given that there are two equal angles. A isosceles right triangle has the same characteristics of an isosceles triangle but has a 90 degree angle.

Since the sum of all the angles in a triangle is 180 degrees, we can subtract the 90 degrees from the right triangle and divide the remainder by 2. This would be 45 degrees.

1.) 180 - 90 = 90

2.) = 45

Hope this was useful. Cheers.
