In cyclic quadrilateral PQRS, ∠P = 100^o and  ∠Q = 70^o . Find ∠R and ∠S.

PT is a tangent to the circle at a point T. PAB is a secant line, PA = 16cm AB = 9cm. Find PT.

PA is tangent segment from the point P to a circle with centre C. If PA = CA then ∠CPA

O is the centre of the circle PA and PB are tangents. ∠ACB = 108^o ∠P =

The incentre of ΔABC is I. If ∠BIC = 110^o and ∠B = 50^o, ∠C =

The angle made by an arc at a point on it and that is the alternating segment are (3x - 10) and (2x + 30) what is x.

A line that intersect a circle in two distinct point is called

The tangents at the ends of a diameter of a circle are

There is one and only one ________ at any point A on the circle
 

A tangent segment is drawn to a circle from a point 13cm away from the center of the circle. If the diameter is 10cm the length of the tangent segment is
