Exterior Angle and Triangle Sum Theorem Task Cards
In this set of task cards, students will use the Exterior Angle Theorem and the Triangle Sum Theorem to solve problems. All of the problems are diagrams where students will solve for x or find a missing angle measure. Students will need to solve basic linear equations to solve the problems.
The problems are of various difficulty. Make sure these problems are appropriate for your students - download the preview and look at the thumbnails to see problem examples. This set includes 20 task cards and the solutions. The cards are given in two different ways: with QR codes and without QR codes.
Task cards are a great way to help students review or to use as warm-ups throughout the unit. QR codes are a great way to integrate technology in your classroom and keep students interested.
