Draw a circle of radius 3 cm. Mark a point P at a distance of 5 cm from the centre of the circle drawn. Draw two tangents PA and PB to the given circle and measure the length of each tangent. Solution: Steps of Construction: Draw a circle with centre O and radius 3 cm. From O, take a point P such that OP = 5 cm Draw a bisector of OP which intersects OP at M. With centre M, and radius OM, draw a circle which intersects the given circle at A and B. Join AP and BP. AP and BP are the required tangents. On measuring AP = BP = 4 cm Question 2. Draw a circle of diameter of 9 cm. Mark a point at a distance of 7.5 cm from the centre of the circle. Draw tangents to the given circle from ...
