Determining Angles in Shapes
- Identify acute, right, obtuse, and reflex angles in a drawing.
- Count how many of each type of angle a shape has.
- Use angle size clues (smaller than 90°, exactly 90°, between 90° and 180°, greater than 180°) to sort angles correctly.
- Pay attention to where the angle is formed at a vertex so you don’t count the wrong corner.
