36@shubhodip -> Hi! dear.... there can be no such case that A=C=90 B≠D≠90......????
In the above figure we see four line segments intersecting at
A,B,C and D respectively. LA = 900, LC = 900.
Surely, LB = LD = 900. So how can we prove it theoretically...!
Practically its true and obvious but can that be proved theoretically..?
(i'm confused)

21u cant prove it because not always B =D=90° ( it must be given AD and BC are parallel)
draw figure in some other fashions u will get cases where A=C=90 B≠D≠90
3621how about that ?
actually quadrilaterals inscribed in a circle which has only one diagonal passing through the center of the circle are all of such form...
