| Term | Definition | | :--- | :--- | | 1. | A. A segment whose endpoints lie on the circle. | | 2. External Segment | B. A line that intersects a circle at exactly two points. | | 3. Chord | C. The part of a secant segment that lies outside the circle. | | 4. Tangent Line | D. A line that touches a circle at exactly one point. | Part 2: Secants Intersecting Inside the Circle Rule: If two secants intersect inside a circle, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
