A circle is inscribed in a right-angled triangle with sides 8 cm, 15 cm, and 17 cm. The radius of the inscribed circle is:

The angle between a tangent to a circle and the radius through the point of contact is:

A line that intersects a circle at two distinct points is called a:

A circle touches the side BC of a ΔABC at P and touches AB and AC when produced at Q and R respectively. If the perimeter of ΔABC is 20 cm, what is the length of AQ?

A circle can have a maximum of how many parallel tangents?

Two circles touch each other externally at point C. A common tangent AB is drawn touching the circles at A and B. Then, the measure of ∠ACB is:

If two tangents inclined at an angle of 60° are drawn to a circle of radius 3 cm, then the length of each tangent 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 what is the measure of ∠POA?

How many tangents can be drawn to a circle from a point lying inside the circle?

A parallelogram circumscribing a circle is always a:

In a circle with centre O, PA and PB are tangents from an external point P. If ∠OPB = 30°, then ∠AOB is:

PQ is a tangent to a circle with centre O at point P. If ΔOPQ is an isosceles triangle, then ∠OQP is equal to:

How many tangents can be drawn to a circle at a single point on the circle?

A tangent PQ at a point P of a circle of radius 5 cm meets a line through the centre O at a point Q so that OQ = 13 cm. What is the length of PQ?

The angle between two tangents from an external point P to a circle is supplementary to the angle subtended by the line segment joining points of contact at the center. If the angle at the center is 130°, find the angle between the tangents.

From a point P, which is 10 cm away from the centre of a circle, a tangent PT of length 8 cm is drawn. What is the radius of the circle?

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

Two concentric circles are of radii 13 cm and 5 cm. What is the length of the chord of the larger circle which touches the smaller circle?

The lengths of tangents drawn from an external point to a circle are:

A quadrilateral ABCD is drawn to circumscribe a circle. If AB = 12 cm, BC = 15 cm and CD = 14 cm, what is the length of AD?
