  1. Geometry Honors Section 9.2Tangents to Circles

  2. A line in the plane of a circle may or may not intersect the circle. There are 3 possibilities.

  3. A *secant to a circleis a line which intersects the circle in two points.

  4. A *tangent to a circleis a line, in the plane of the circle, that intersects the circle in exactly one point.This point of intersection is known as the _______________ point of tangency.

  5. Tangent TheoremIf a line is tangent to a circle, then it is perpendicular to the radius drawn to the point of tangency.

  6. A segment is tangent to a circle if the segment is part of a tangent line and one endpoint is the point of tangency.

  7. Tangent Segments TheoremIf two segments are tangent to a circle from the same exterior point, then the tangent segments are congruent.
