If PT is a tangent at T to a circle whose centre is O and OP = 17 cm, OT = 8 cm, find the length of the tangent segment PT.
Given that O is the center of the circle and OP =17 cm and the radius of the circle OT=8cm.
We need to find the length of the segment PT.
The line PT is the tangent line to the circle at the point T, the line through the centre is perpendicular to PT.
