The line segment joining the point of contact of two parallel tangent to a circle is a ___________ of the circle.

In fig, PA = 9cm QB = 6cm, then length of PQ is

O is the center of the circle. PA and PB are tangents from an external point P. If ∠AOB = 125^o then measure of ∠P =

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

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

The tangent at any point of a circle is perpendicular to the _________ through the point of contact.

From a point P, the length of the tangent to a circle is 15cm and distance of P from the centre of the circle is 17cm. Then what is the radius of the circle:

The number of diameters of a circle a/ are

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

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