yes i m say....!!!!!!

Answer 2

In a semi circle the angle is equal to 90° if we make a quadrilateral like this below we can prove two angles equal to 90° with a reason tht each angle in semi circle in 90°
If the two angles are 90 then opposite angle to them is also 90 because opposite angles of cyclic quadrateral is 180
Since all angles are 90 hence we can prove that cyclic quadrilateral is recangle
