    If we draw 4 lines AB ,BC , Cd and DA as shown we form a quadrilaterl with 4 right angles because a diameter subtends an angle of 90 degrees at the circumference

    diagonals are equal and bisect each other at right angles so a square.

    Also the 4 lines each subtend an angle of 90 degrees at the center . Therefore they are all equal in size. So ABCD is a square.
