Angle Sum Theorem | 8th Grade Math Quick Reference Sheet | Cheat Sheet

This 8th Grade Math Quick Reference Sheet explains what the angle sum theorem is and step-by-step examples for how to use it.

This info sheet can be used for students to review the angle sum theorem after they've already learned about the concept or as an already complete notes page to help teach the concept initially. This is also a great resource to give to parents or substitute teachers so they're better able to help their student(s).
