Question

Plzz solve the above question....

Answer 1

X = The point between A and B
There is a rule that any diameter bisects a chord, so AX = BX
AXD = 90 degrees because 180-90=90
DX = DX because of reflexive property

Therefore triangle AXD and BXD are congruent by SAS

Any two triangles that are congruent have congruent sides and angles which are corresponding, so AD = BD
