Question

in triangle ABC, AD is the perpendicular bisector of BC show that the triangle ABC is an isoscales Triangle in which AB= AC.​

Answer 1

Step-by-step explanation:

if AD is perpendicular bisector oh BC then 90'

therefore angle1) AD= AD , ADis perpendicular bisector.

2)angleADB=angleADC,90'angle

therefore AB=AC,byC.P.C.T

Answer 2

Step-by-step explanation:

Since, in triangle ABC,

AB=AC----given

therefore, in triangle ABC,

angle ABC=angle ACB

thus, triangle ABC is an isosceles triangle
