Question

In ∆ABC, The bisector AD of angle A is perpendicular to side BC
Show that; AB = AC​

Answer 1

Step-by-step explanation:

∴ AB = AC | C.P.C.T.

∴ ∆ABC is an isosceles triangle in which

AB = AC.

(iv) AP is the perpendicular bisector of BC.

Given: ∆ABC and ∆DBC are two isosceles triangles on the same base BC and vertices A and D are on the same side of BC.
