About Geometry Worksheet Assignment 10.22:
Assignment 10.22 is an introduction to the theorem about the lengths of segments of intersecting secants
Prerequisite Skills: Measure lengths to the nearest cm (Assignment 1.11). Identify arcs intercepted by inscribed angles (Assignment 10.10). Solve algebraic equations with one variable.
Theorem: For two secants intersecting in the exterior of a circle, the products of the lengths of each secant segment and its exterior segment are equal.
