Mathematics
Draw a circle of radius 4 cm. Mark its centre as C and mark a point D such that CD = 7 cm. Using ruler and compasses only but not using the centre of the circle, construct two tangents from D.
Answer
Steps of construction :
Construct a circle with centre as C and radius = 4 cm.
Mark a point D at a distance of 7 cm from the centre. Join CD. Draw its perpendicular bisector to meet CD at M.
With M as centre and CM (or MD) as radius, draw a circle. Let this circle intersect the given circle with centre as C at points A and B.
Join DA and DB.
