###### Important questions from CBSE Board examination based on Circles – 10th Maths
1. Draw a line segment AB = 8 cm. Taking AB as diameter a circle is drawn with centre O. Now draw OP is perpendicular AB. Through P draw a tangent to the circle.
2. Draw a circle of radius OP = 3 cm. Draw ∆POQ = 45° such that OQ = 5 cm. Now draw two tangents from Q to given circle.
3. Draw a circle with centre O and radius 3.5 cm. Draw two tangents PA and PB from an external point P such that ∆APB = 45°. What is the value of ∆AOB + ∆APB?
4. Draw a circle of radius 4 cm. Now draw a set of tangents from an external point P such that the angle between the two tangents is half of the central angle made by joining the points of contact to the centre.
5. Draw a line segment AB = 9 cm. Taking A and B as centres draw two circles of radius 5 cm and 3 cm respectively. Now draw tangents to each circle from the centre of the other.
6. Draw a circle of radius 3.5 cm with centre O. Take point P such that OP = 6 cm. OP cuts the circle at T. Draw two tangents PQ and PR. Join Q to R. Through T draw AB parallel to QR such that A and B are point on PQ and PR.
7. Draw a circle of diameter 7 cm. Draw a pair of tangents to the circle, which are inclined to each other at an angle of 60°.
8. Draw a circle with centre O and radius 3.5 cm. Take a horizontal diameter. Extend it to both sides to point P and Q such that OP = OQ = 7 cm. Draw tangents PA and QB one above the diameter and the other below the diameter. Is PA || BQ?
