- Acute angle is less than 90°.
- Obtuse angle is greater than 90°.
- Right angle is exactly 90°.
- Straight angle is equals to 180°.
- Reflex angle is greater than 180°.
- Full Rotation is exactly 360°
Negative and Positive Angles.When measuring from a line:
- a positive angle goes counterclockwise (opposite direction that clocks go).
- a negative angle goes clockwise.
