Question

prove if the bisector of the vertical angle of a triangle, then the triangle is isosceles

Answer 1

Step-by-step explanation:

Given: In quadrilateral ACBD, AC = AD and ABbisects ∠A. To Prove: ∆ABC ≅ ∆ABD. ∆ABC is an isosceles triangle in which AB = AC. ... 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.
