Types of angles 1 Acute angle 2 Right

Here are the types of angles:

1. Acute angle: An angle that measures less than $90^\circ$.
2. Right angle: An angle that measures exactly $90^\circ$.
3. Obtuse angle: An angle that measures greater than $90^\circ$ but less than $180^\circ$.
4. Straight angle: An angle that measures exactly $180^\circ$.
5. Reflex angle: An angle that measures greater than $180^\circ$ but less than $360^\circ$.
6. Full angle (or Complete angle): An angle that measures exactly $360^\circ$.
