Question

draw a pair of tangents to a circle of radius 4cm which are inclined to each other at an angle of 120 degree​

Answer 1

Step-by-step explanation:

step 1: draw a circle of radius 4 cm and centre 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 an angle of 60⁰ with OA.

step 5: draw a perpendicular to OB at point B.

let these perpendicular intersect at P.

PA and PB are required tangets inclined at angle of 120⁰
