Answer:
Let us consider a parallelogram ABCD such as diagonals AC and BD intersect at O
Also, in ||gm ABCD, AB = DC & AB || DC and AD = BC & AD || BC (known)
In triangles AOB and DOC
Angle BAO = Angle DCO (interior opposite angles)
AB = DC (Known)
Angle ABO = Angle CDO Interior opposite angles)
Hence, by ASA congruency, triangle AOB is congruent to triangle DOC
So, AO = CO and BO = DO
Thus the two diagonals bisect each other (Hence proved)
