Question

What is the measure of acute angles of an isosceles right angled triangle in grade and circular measure?

Answer 1

Step-by-step explanation:

In Isosceles right angled triangle the measure of the acute angle is 45°. Because in isosceles right angled triangle one angle is 90° and other two are equal due to angles opposite to equal sides are equal. So by angle sum property of triangle we get 45° .

Answer 2

Step-by-step explanation:

In an isosceles triangle two angles are congruent.

One ongle is 90° . let other two angles be a°

a°+a°+90° = 180° ( sum of the measures of 3 angles of a triangle is 180°)

2a = 180–90 = 90 °

a = 90/2 = 45°

The measure of each acute angle of an isosceles right angled triangle is 45°
