Cyclic Quadrilateral
Draw a circle of with centre O. Mark four points A, B, C and D on the circumference of the circle.
Join A to B, B to C, C to D and D to A.
Thus, a quadrilateral ABCD is formed inside the circle.
Definition of the Cyclic Quadrilateral?
A quadrilateral is said to be cyclic if all its vertices lie on a circle. In the fig. A, B, C and D are the vertices of the cyclic quadrilateral.
Now let us know the important property of the Cyclic Quadrilateral.
In a cyclic quadrilateral, the opposite angles are supplementary. Therefore, in the fig. angle A plus angle C is equal to the 180 degrees and angle B plus angle D is equal to the 180 degrees.
