Question
Draw a circle of radius 4.5 cm. Draw two tangents to this circle so that the angle between the tangents is 60°.
Solution
Steps of construction:
- Draw a circle with centre O and radius BC = 4.5 cm.
- Draw arcs making an angle of 180° – 60° = 120° at O such that ∠AOB = 120°.
- At A and B, draw two rays making an angle of 90° at each point which meet each other at point P, outside the circle.
- AP and BP are the required tangents which make an angle of 60º with each other at P.
