Question

How to prove theorem angles opposite sides are equal

Answer 1

Answer:

This result can be proved in many ways

Step-by-step explanation:

Proof :

You may draw an isosceles triangle ABC in which AB =AC We need to prove that angle B =angle C.

Draw the bisector of angle A and D be the point of intersection of this bisector of angle A And BC

you will observe

AB=AC (Given)

Angle BAD =Angle CAD

AD =AD (Common)

∆BAD congruent to ∆CAD. By SAS rule
