Question

Draw a circle of radius $4$ cm. Draw two tangents to the circle inclined at an angle of ${60}^{\circ }$ to each other.

Answer 1

Step 1 : Draw a circle of radius $4$ cm and with centre as O.
Step 2 : Take a point A on the circumference of the circle and join OA. Draw a perpendicular to OA at point A.
Step 3 : Draw a radius OB, making an angle of ${120}^o=({180}^o-{60}^o)$ with OA.
Step 4 : Draw a perpendicular to OB at point B. Let both the perpendiculars intersect at point P. PA and PB are the required tangents at an angle of ${60}^o$.
