Question

· Draw a pair of tangents to a circle of radius 3 cm which are inclined to each other at an
angle of 60°
​

Answer 1

Step-by-step explanation:

1. Draw a circle of r=3cm
2. Draw a radius such that it form an angle of 120 degrees with the previous radius drawn
3. Now make angles of 90 degrees on the points where the radius touches the circumference of the circle
4. Now extend the lines drawn when the angles of 90 degrees were made
5. Mark the point of intersection of both the lines as A
6. Mark the centre as O, and also mark the points when radius touches circumference as B and C
7. You will observe that AB =AC (tangents drwan from an external point)
8. Also the angle BAC = 60degree
