Answer 2

Answer-

Step by step explination-

Take a quadrilateral ABCD, AC and BD are diagonals which intersect at O.

In triangle AOB and Triangle AOD

DO=OB ( Mid point)

angle AOB = angle AOD (right angle)

therefore triangle AOB is congruent to triangle AOD

So, AB =AD

In the same way we can prove that

AB = BC = CD = AD

Therefore ABCD is a rhombus

Hence proved
