What are the Properties of Cyclic Quadrilaterals? Cyclic quadrilateral If all four points of a quadrilateral are on circle then it is called cyclic Quadrilateral. A quadrilateral PQRS is said to be cyclic quadrilateral if there exists a circle passing through all its four vertices P, Q, R and S. Let a cyclic quadrilateral be such that PQ = a, QR = b, RS = c and SP = … [Read more...] about What are the Properties of Cyclic Quadrilaterals?
Number Of Tangents From A Point On A Circle (i) There is no tangent passing through a point lying inside the circle. (ii) There is one and only one tangent passing through a point lying on a circle. (iii) There are exactly two tangents through a point lying outside a circle. Length Of Tangent The length of the line segment of the tangent between a given point and the given … [Read more...] about Number Of Tangents From A Point On A Circle
