If a tangent from point P touches the circle at point T, and the radius OT is 6 cm, what is the length of PT if PT is the tangent?
Tangent to a Circle – A tangent to a circle is a line that touches the circle at exactly one point, and the radius drawn to the point of tangency is perpendicular to the tangent.
Properties of Tangents – The length of a tangent from an external point to a circle is equal to the square root of the difference between the square of the distance from the external point to the center of the circle and the square of the radius.
