Question

Draw a Circle of radius 3cm. Construct tangents to the circle from an external point 10cm away from its centre.


​

Answer 1

Answer:

Step-by-step explanation:  

Given: A circle with centre O radius 3 cm.

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.
