• 6. 9-1 Tangents, Arcs, and Chords <ul><li>Radii – Plural of radius. All radii of a circle are congruent. </li></ul><ul><li>Chord – A segment whose endpoints are points on the circle. </li></ul>P radii chord
• 7. 9-1 Tangents, Arcs, and Chords <ul><li>Secant – A line that intersects a circle in two points. </li></ul><ul><li>Tangent – A line that intersects the circle in exactly </li></ul><ul><li>one point. </li></ul>P secant tangent
