Triangle ABC is an isosceles triangle with `AB=AC` side BA produced to D such that `AB=AD`. Then find `angleBCD =90^@`

triangleABC is an isosceles triangle in which AB= AC. Side BA is produced to D such that AD = AB. Show that angleBCD is a right angle.

DeltaABC is an isosceles triangle with AB=AC , side BA is produced to D such that AB=AD. Prove that angleBCD is a right angle.

DeltaABC is an isosceles triangle with AB = AC. Side BA is produced to D such that AB = AD. Prove that angleBCD is a right angle.

In the fig. ABC is a triangle in which AB=AC side BA is produced to D such that AB=AD prove that angle=BCD=90^@
