Steps of construction:
- Draw circle with centre O and radius OA = 5 cm, .
- Mark another point B on the circle such that ∠AOB = 120°, supplementary to the angle between the tangents. Since the angle between the tangents to be constructed is 60°.
∴ ∠AOB = 180° – 60° = 120°.
3.Construct angles of 90° at A and B and extend the lines so as to intersect at point P.
4. Thus, AP and BP are the required tangents to the circle.

- draw a circle of radius 3.4 cm. Draw a chord MN of length 5.7 cm in it construct tangents at M and N to the circle.
- Construct a tangent to circle of radius 4 cm through a point P on its circumference.
- Construct tangents to a circle with centre O from an external point P.
- Draw a circle of radius 4 cm. Take a point P outside the circle. Without using the centre of the circle, draw two tangents to the circle from point P.
- Draw a circle of radius 1.5 cm. Take a point P outside it. Without using the centre, draw two tangents to the circle from the point P.
- Draw a pair of tangents to a circle of any convenient radius, which are inclined to the line joining the centre of the circle and the point at which they intersect at an angle of 45o.
- Construct a tangent to a circle of radius 4 cm from a point on the concentric circle of radius 6 cm and measure its length. Also verify the measurement by actual calculation.
- Construct a tangent to a circle of radius 4 cm from a point which is at a distance of 6 cm from its centre.
