With this Smartboard lesson, students will learn to identify many different types of angles. They will fill out a table that has them not only write a definition of each, but also draw examples and non-examples to further their comprehension. The students will practice recognizing different angles as well as finding the measure of missing angles. Great lesson for your geometry unit and is part of the 7th grade common core state standards. I use this lesson after students have already learned the triangles and quadrilaterals (and already recognize acute, right, and obtuse angles).
