Question

Draw a circle of radius $4.5$ cm. Draw two tangents to the circle so that the angle between the tangents is ${60}^o$.

Answer 1

Step 1 : Draw a circle of radius $4.5$ cm with center O.

Step 2: Take a point A on the circle join OA.

Step 3: Draw a perpendicular to OA at A.

Step 4: Draw a radius OB making a angle ${120}^{\circ }({180}^{\circ }-{60}^{\circ })$ with OA

Step 5: Draw a perpendicular to OB at B. Let these both perpendicular meet at P.

$\therefore$ PA and PB are the required tangents with angle of inclination ${60}^{\circ }$.
