Angles can be classified by size:
- Acute angle: between 0° and 90°
- Right angle: equal to 90°
- Obtuse angle: between 90° and 180°
- Straight angle (line): equal to 180°
- Reflex angle: between 180° and 360°
In a shape, an angle can be an interior angle or an exterior angle.
Angles that sum to 90° are called complementary angles.
Angles that sum to 180° are called supplementary angles.
