Question

in a right isosceles triangle what is the measure of the acute angles

Answer 1

45 degree should be

Answer 2

In a triangle, the sum of all angles is equal to 180 degrees, and one of the angles is 90, since it's a right angled triangle too,

Let angles be A,B and C

A + B + C = 180

Where A = B as it is an isoceles triangle,

2A + 90 = 180
2A = 90

A = 90 = B.... which are the two acute angles.
