Determining Visually
Each worksheet has 20 problems determining if an angle is acute, obtuse, straight or right.
Student Objectives
- Identify whether an angle is acute, right, obtuse, or straight by looking at it.
- Compare an angle to a right angle as a quick visual benchmark.
- Notice when an angle is smaller than 90°, exactly 90°, between 90° and 180°, or exactly 180°.
- Use the shape and direction of the rays to classify angles even when they are rotated.
