This worksheet is designed to replace a lecture on the topic of what are typically called the power-secant theorems for circles.
The fifth page is a reference sheet, which I run off on a separate sheet of colorful paper for my students, so they can easily find it.
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
Immediately before this worksheet, I use the mini lesson named 'Applying Circle Formulas Chords Secants Tangents Student Notes Spring 2014' (http://www.teacherspayteachers.com/Product/Applying-Circle-Formulas-Chords-Secants-Tangents-Student-Notes-Spring-2014-1269853
), and immediately after this worksheet, I use the worksheet named 'Transformations of Quadratic Functions for Geometry Spring 2014' (http://www.teacherspayteachers.com/Product/Transformations-of-Quadratic-Functions-for-Geometry-Spring-2014-1269868
