This worksheet is intended to replace a lecture on exterior angles of triangles, as well as parallel and perpendicular lines. It is assumed that students have some familiarity with the interior angles of polygons, and that students have worked with slope-intercept form of a line in the past.
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.
