Rule of Construction:
(i) I have drawn a circle with centre O and radius 4 cm.
(ii) I joined O and P.
(iii) I bisected the line segment OP at the point X.
(iv) Taking X as centre and radius equal to XO, I drew a semicircle which intersects the given circle (with centre O) at the point T.
(v) I joined P and T, and extended it.
∴ PT is the tangent to the circle with centre O from the external point P.
