Acute Angle vs Obtuse Angle — Comparison Table
| Basis | Acute Angle | Obtuse Angle |
|---|---|---|
| Measurement Range | 0° to 90° | 90° to 180° |
| Comparison to Right Angle | Smaller than a right angle | Larger than a right angle |
| Appearance | Sharp and pointed | Wide and open |
| Examples | 30°, 45°, 60°, 75° | 120°, 135°, 150° |
| Clock Hand Example | 1:00 position forms acute angle | 4:00 position forms obtuse angle |
Key Points
- Acute angles are less than 90 degrees
- Obtuse angles are more than 90 degrees but less than 180 degrees
- A right angle is exactly 90 degrees
- Acute and obtuse angles are common in geometry and everyday objects
