Question

Draw a circle with radius 3cm and construct a pair of tangent from a point 8cm away from the centre​

Answer 1

★$\mapsto\bf{Given:}$★

A circle with centre O radius 3 cm.

★$\mapsto\bf{Required:}$★

To construct the pair of entre tangents.

Steps of Construction:

(i) Draw a circle of radius 3 cm.

(ii)Take an external point P which is 10 cm away from its centre. Join OP.

(i) Bisect the line segment OP = 10 cm. Let the point of bisection be M.

(ii)Taking M as centre and OM as radius, drwa a circle. Let it intersect the given circle at the points Q and R.

(iii) Join PQ and PR.

These are the required tangents
