Explain the difference between a tangent segment and a secant segment.
A tangent segment only touches the circle in one point; they sort of kiss. The segment doesn’t actually go through the circle. If a wheel was rolling on a table top, the table top would be tangent. A secant segment intersects in two points. It actually pierces or goes through the circle. In a tangent segment, no part of it is in the interior of the circle. With a secant, there is a part in the interior, called a chord
