Question

In isosceles triangle one base angle is twice of vertex angle. Find the three angle of the triangle.​

Answer 1

Answer:

if one base angle be x° then other will be also x°

as triangle is isosceles..

ATQ vertex angle = 2x°

using angle sum property of triangle..

x + x + 2x = 180°

4x = 180°

x = 45°

then the angles of triangle are 45°, 45° and 90°
