### PRODUCT DESCRIPTION

This worksheet is designed to replace a lecture on the topic of isosceles and equilateral triangles. This lesson focuses on the fact that if two sides of a triangle are congruent, the opposite angles (the base angles) are congruent, and vice versa.

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 worksheet named 'Angles Problem Solving Fall 2013' (http://www.teacherspayteachers.com/Product/Angles-Problem-Solving-Fall-2013-1072487), and immediately after this worksheet, I use the worksheet named 'Midsegments Circumcenters and Angle Bisectors Fall 2013' (http://www.teacherspayteachers.com/Product/Midsegments-Circumcenters-and-Angle-Bisectors-Fall-2013-1070678)
