Take notes on the following topics.
Section 11.4 Angle Measures and Segment Lengths Vocabulary Secant (p. 607) A secant is a line, ray, or segment that intersects a circle at two points. Theorem 11-11 The measure of an angle formed by two lines that (1) intersect inside a circle is half the sum of the measures of the intercepted arcs. (2) intersect outside a circle is half the difference of the measures of the incepted arcs. Theorem 11-12
For a given point and a circle, the
product of the lengths of the two segments from the point to the
circle is constant along any line through the point and circle. (See
class notes on this theorem)
