Question

Prove that on extending equal sides of an isosceles triangle, bisectors of angles
which are formed below the base form an isosceles triangle.​

Answer 1

Answer:

If A is greater than B then bisector of B is larger than that of A bcz larger angle has smaller bisector but since both bisector are equal so this is not possible as bisector are given equal. Hence side opposite to equal angle are equal so the triangle is isosceles. Hence the triangle is isosceles .
