📘 What Are Co-Terminal Angles?
Co-terminal angles are angles that share the same terminal side when drawn in standard position. This means they have the same initial and terminal sides but may differ by a full rotation (360° or (2π) radians).
To find co-terminal angles, you can add or subtract multiples of 360° (or 2π) to a given angle.
Formula:
θ ± 360° × n (in degrees)
θ ± 2π × n (in radians), where n is an integer.
Example: Co-terminal angles of 45° include:
45° + 360° = 405°, 45° - 360° = -315°, etc.
