Define a ‘Cyclic Quadrilateral’ .

Sum of opposite angles in a cyclic quadrilateral is …………

ABCD is a cyclic quadrilateral then angleA+angleC = ……….

If A,B,C,D are the angles of a cyclic quadrilateral then sinA+sinB=

ABCD is a cyclic quadrilateral. If angleA - angleC = 20^@ , find angleC .

State the converse of the following theorem. "The pairs of opposite angles of a cyclic quadrilateral are supplementary".

The area of any cyclic quadrilateral ABCD is given by A^(2)=(s-a)(s-b)(s-c) (s-d) , where 28 = a + b + c + d, a, b,c and d are the sides of the quadrilateral. Now consier a cyclic quadrilateral ABCD of area 1sq.unit and answer the following questions: The minimum perimeter of the quadrilateral is

If A, B, C, D are angles of a cyclic quadrilateral then P.T sin A - sin C = sin D - sin B .
