Hello mate =_=

Solution:

It is given that ABCD is a cyclic quadrilateral. Also, AC and BD are two diameters of circle having centre O.

We need to prove that ABCD is a rectangle.

BD is a diameter which means that ∠BCD=∠DAB=90°           ......... (1)

(Angle in a semi-circle is equal to 90°)

Similarly, AC is a diagonals which means that ∠ABC=∠ADC=90°  .....(2)

(Angle in a semi-circle is equal to 90°)

From (1) and (2), we can notice that opposite angles of quadrilateral ABCD are equal which makes it a parallelogram.

Also, all the corner angles are equal to 90° which makes it a rectangle.

I hope, this will help you.

Thank you______❤
