This worksheet is designed to replace a lecture on the topic of parallel lines and transversals.

I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about: transversals, the three basic formulas that result when a transversal intersects parallel lines:
acute = acute
obtuse = obtuse
acute + obtuse = 180

It also covers vocabulary terms such as corresponding angles, alternate interior angles, alternate exterior angles, consecutive interior angles, (also called same side interior angles), linear pairs, and vertical angles. 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 'Constructions Day 2 Fall 2013' (http://www.teacherspayteachers.com/Product/Constructions-Day-2-Fall-2013-1082528), and immediately after this worksheet, I use the assessment named 'Geometry Group Practice Test Introductory Material Fall 2013' (http://www.teacherspayteachers.com/Product/Geometry-Group-Practice-Test-Introductory-Material-Fall-2013-1269942)
