Question

construct a pair of tangent to a radius of circle 4 cm which are inclined at angle of
90°
40°​

Answer 1

Answer:

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
