Question

Angle opposite to equal sides of an isosceles triangle are equal. PROVE IT..​

Answer 1

Answer:

Thus we can say that ΔBAD is equal to ΔCAD, by SAS congruent rule, where 2 sides and one angle of one triangle is equal to 2 sides and one angle of another triangle. Thus we can say that ∠ABD is equal to ∠ACD, as both triangles are equal. Hence we proved that the angles opposite to equal sides are equal...
