Question

Prove that angles opposite to equal sides of an isosceles triangle are equal.​

Answer 1

Step-by-step explanation:

As both the sides are equal..

The two angles formed by drawing a bisector are equal..

The bases of the triangle formed by bisecting the triangle are equal..

So, as per side angle side.. both the triangles formed by bisecting the triangle are congruent

Therefore, angles opposite to equal sides of an isosceles triangle are equal (CPCT)
