Question

prove that, if the bisector of <BAC of ∆ABC is perpendicular to side BC, then ∆ABC is an isosceles triangle.​

Answer 1

Step-by-step explanation:

In Δ ABC, the bisector of ∠ BAC is perpendicular to the base BC. We have to prove that the ΔABC is isosceles. Hence, ΔABC is isosceles. Concept: Isosceles Triangles - Isosceles Triangle : If Two Angles of a Triangle Are Equal, the Sides Opposite to Them Are Also Equal.
