Secants and Tangents

Secants and Tangents

Secants and Tangents. A secant to a circle is a line that intersects the circle at two points. Secants and Tangents. A tangent is a line in the plane of the circle that intersects the circle at exactly one point. This point is the point of tangency. Tangent Theorem.

Lesson 1.5

Lesson 1.5

Lesson 1.5. Division of Segments and Angles. Segment Bisector. A point (or a segment ray, or line) that divides a segment into two congruent segments bisects the segment. The bisection point is called the midpoint of the segment. Examples.
