Question

In the figure

AB = AD, BC = CD
prove that ∠ABC = ∠ADC​

Answer 1

I hope it will help U.

Answer 2

AB = AD [Given]

BC = CD [Given]

AC = AC [Same line segment]

So, ΔABC ≅ ΔADC [By SSS congruence criteria]

So, ∠ABC = ∠ADC [CPCT (Corresponding parts of congruent triangles)]

Hence, proved.
