About Angles

Angle Measurement: Angles can be measured in degrees (°) or radians (rad)

Conversion: 180° = π radians, so 1° = π/180 rad and 1 rad = 180/π °

Key Concepts:

  • Reference Angle: Acute angle to x-axis (0° to 90°)
  • Coterminal Angles: Angles that share the same terminal side
  • Complementary: Two angles that add to 90°
  • Supplementary: Two angles that add to 180°
  • Standard Position: Vertex at origin, initial side on positive x-axis
  • Arc Length: Distance along circle circumference (s = rθ)
  • Quadrants: I (0°-90°), II (90°-180°), III (180°-270°), IV (270°-360°)
