Construct a tangent of a circle of radius 4cm from a point on the concentric circle of radius 6 cm.
Given: Radii of two co-centric circles.
To do: To construct a tangent of the circle with radius 4 cm from a point on the co-centric circle of radius 6cm.
Solution:
Steps of construction
1. Draw two concentric circle with centre O and radii 4 cm and 6 cm Take a point P on the outer circle and then join OP
2. Draw the perpendicular bisector of OP. Let the bisector intersects OP at M
3. 
With M as the center and OM as the radius, draw a circle. Let it intersect the inner circle at A and B.
With M as the center and OM as the radius, draw a circle. Let it intersect the inner circle at A and B.4. Join PA and PB.
Therefore, PA and PB are the required tangents.
