Step-by-step explanation:

In an isosceles triangle , base angles are equal

Let vertex angles be x

Then, Base angles will be 2x and 2x

SUM OF ANGLES OF TRIANGLE IS 180°.

Therefore,

2x + 2x + x = 180°

5x = 180°

=> x = 36°

Vertex angle = x = 36°

Base angles = 2x = 36° × 2 = 72° & 72°

Therefore all angles are 36 , 72 and 72
