Answer 1

We know that,

Opposite angles of cyclic quadrilateral are suplementry

So, a +b = 180° --------(1)

And,

Opposite angles of paralellogram are equal..

a = b

Now,

On Substituting the value of a, in equation (1),we get

2a = 180°

=> a = 90°

And we know that a parallelogram whose one angle is 90°,is rectangle

Hence Proved.
