Answer:
The tangent-secant theorem describes the relation of line segments created by a secant and a tangent line with the associated circle. This result is found as Proposition 36 in Book 3 of Euclid's Elements.
Tangent is a line that intersects a circle at only one point. i.e. it only touches the circle. A secant is a line that intersects the circle at 2 distinct parts.
The secant line is the red line to the right that passes through two points on the curve. The tangent line is the green line that just grazes the curve at a point.
