Question

Since 09 and OR are radii of the circle with centre O, PQ and PR are tangents to the circle.
2. Construct a tangent to a circle of radius 4 cm from a point on the concentric circle of
radius 6 cm and measure its length. Also verify the measurement by actual calculation.
Required : Draw two concentric circles with radii 4 cm and 6 cm and centre O. Then, draw tangents
to the smaller circle from a point P on the bigger circle. Also measure the lengths of
the tangents and verify it by calculations.
