1. There are three classifications of angles: acute angles which are less than 90 degrees, right angles which are exactly 90 degrees, and obtuse angles which are greater than 90 degrees. 2. The document provides examples and definitions of each angle classification and asks students to identify examples of each type of angle from images. 3. Students are expected to learn to identify, define, and classify angles as acute, right, or obtuse.
