Angle Equations
Complementary Angles
- Two angles that add up to 90°
- Example: ∠A + ∠B = 90°
- Each angle is called a complement of the other
Supplementary Angles
- Two angles that add up to 180°
- Example: ∠A + ∠B = 180°
- Each angle is called a supplement of the other
Right Angles
- An angle that measures 90°
- Formed by two perpendicular lines
- Example: ∠A = 90°
Obtuse Angles
- An angle greater than 90° but less than 180°
- Example: 120°, 150°, etc.
Acute Angles
- An angle less than 90°
- Example: 30°, 60°, etc.
Reflex Angles
- An angle greater than 180° but less than 360°
- Example: 210°, 240°, etc.
Straight Angles
- An angle that measures 180°
- Formed by two lines that lie in the same direction
- Example: ∠A = 180°
