A tangent to a circle intersects it in:
A line intersecting a circle in two points is called a:
The maximum number of parallel tangents a circle can have on a given secant is:
The common point of a tangent to a circle and the circle is called:
From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm. The radius of the circle is:
If tangents PA and PB from a point P to a circle with centre O are inclined to each other at an angle of 80°, then ∠POA is equal to:
Tangents TP and TQ are drawn to a circle with centre O from an external point T such that ∠POQ = 110°. Then ∠PTQ is equal to:
