Students find the measures of angles created when parallel lines are cut by a transversal in this activity that doubles as classroom decor. Angle relationships include: corresponding, alternate interior, vertical, same-side interior, alternate exterior

Two pages of introduction to polygon vocabulary, interior angle sum, exterior…

These hands on geometry lessons are such a great way to help kids see the relationship between the interior and exterior angles in triangles! This free download is simple to use and includes teaching tips and an answer key!

This matching activity is a great way to have students practice finding unknown measures of interior and exterior angles of triangles. There are 12 problems students will solve and match up the answers to on the mat. Students need to apply the triangle sum theorem and also use supplementary and complementary angles to solve for the unknown measure. Teacher answer key included! Common Core Aligned: 8.G.5

This product includes one page of guided notes both reviewing with students how to find missing interior angle measurements in triangles and teaching them how to find exterior angle measurements of triangles. The second page is a practice activity for the students where they are finding exterior angle measurements and matching the symbol with their correct answer. The practice could be used immediately after, given as homework, or used as review in the unit.

Full lesson pack: inquiry-based introduction activity, presentation, printables, and algebra applications included (corresponding angles, alternate interior and exterior angles, etc.)

Parallel Lines, Transversals, and their Angles Cheat Sheet and/or Foldable. Create a parallel line foldable or just pass out the cheat sheet, the choice is yours. Great for an interactive notebook. This unit is part of my Parallel Lines Super

Abercrombie’s Angle Adventure (also known as "Angles Untangled") focuses on supplementary and complementary angles and interior and exterior angles of polygons. Students are introduced to Abercrombie, the skateboarder, who takes them along as he sees what he can discover about angles. The product is composed of 40 pages, which contain nine different common core aligned activities, culminated by a unit assessment. Everything you need for your students to master middle school angle…
