Answer 2

Given, A right angle triangle is an isosceles triangle.

Take a right angle triangle ABC where C°is 90°

and the unknowns are angle A°and B°

Let us assume the unknown angle A° be x .

In an isosceles triangle, two base angles are equal. So, Angle C°=angle A° ......(1)

A°+B°+C°=180° (Angle sum property)

90°+x+x=180° .....(from 1)

90°+2x=180°

2x=180°-90°

2x=90°

x=90°/2

x=45°

Therefore, angle A°=45°

angle B°=45°

angle C°=90°

Hope it helps you mate.
