Circle Product Theorems

Activity Overview

Students will use dynamic models to find patterns. These patterns are the Chord-Chord, Secant-Secant, and Secant-Tangent Theorems.

Key Steps

Students will discover the Chord-Chord, Secant-Secant, and Secant-Tangent Product Theorems.
As an extension, students will be asked to solve a few problems applying the theorems learned during the lesson.
