Question

Draw a circle of radius 4.5 cm and a chord PQ of length 7 cm in it. Construct a tangent at P.

Answer 1

• Draw a circle of radius $4.5cm$
• Take a point $P$ on the circle and mark chord $PQ$ of length $7cm$
• Join $P$ with center $O$
• Taking vertex $P$ and base $OP$ draw a perpendicular to $OP$

The perpendicular $X{X}^{\prime }$ is the required tangent.
