Draw a circle of radius 3 cm. Mark a point P at a distance of 5 cm from the centre of the circle. Draw two tangents PA and PB to the given circle and measure the length of each tangent.
Open in App
Solution
The correct option is B 4 cm
Steps Of Construction:
i) Draw a circle with centre O and radius 3 cm.
ii) Mark a point P outside the circle such that OP = 5 cm
iii) Bisect OP and let it intersect OP at Q
iv) With Q as centre, and radius OQ, draw a circle which intersects the given circle at A and B.
v) Join AP and BP.
AP and BP are the required tangents. On measuring AP = BP = 4 cm
