Description
No Protractor Needed! This Google Slides activity is designed to help students classify angles without using a protractor. Students will use a reference angle, such as the corner of a piece of paper, to determine whether the given angle is right, acute, or obtuse. This is a great way to introduce classifying angles by comparing them to a right angle.
