Q. 5

Take a point which is 9 cm away from the centre of a circle of radius 3 cm, and draw the two tangents to the circle from that point.

Answer :

Radius of the circle = 3 cm


Distance of the point from the center = 9 cm.


The steps for construction are:


Step 1: With O as the center draw a circle of radius 3 cm.



Step 2: Mark a point P at a distance of 9 cm from O and join OP.



Step 3: Draw the perpendicular bisector of OP. Let it meet OP at M.



Step 4: With M as center and MO as radius, draw another circle.



Step 5: Let the two circles intersect at X and Y.



Step 6: Join PX and PY. They are required tangents.



Thus, this is the resulting figure.
