Study Notes
Understanding Angles
- Angles can be classified into three types: acute, obtuse, and right.
- An angle is acute if it measures less than 90°.
- An angle is obtuse if it measures more than 90° but less than 180°.
- A right angle measures exactly 90°.
Using a Protractor
- A protractor is a tool used to measure angles in degrees.
- Proper alignment of the protractor is crucial for accurate measurements.
Angle Classifications
- 64° - classified as acute (less than 90°).
- 30° - classified incorrectly in the provided table; should be acute.
- 89° - classified as acute (less than 90°).
- 174° - classified as obtuse (greater than 90°, less than 180°).
- 125° - classified as obtuse (greater than 90°, less than 180°).
- 95° - classified as obtuse (greater than 90°, less than 180°).
- 85° - classified as acute (less than 90°).
- 90° - classified as a right angle (exactly 90°).
- 75° - classified as acute (less than 90°).
Key Observations
- Confusion can arise when distinguishing acute from obtuse angles based on similar ranges.
- Consistent use of a protractor is essential for accurate angle classification.
