Angle Calculator

1. Mode: Select Complementary, Supplementary, or Polygon Internal Angle.
2. Input: Enter the known angle or number of polygon sides.
3. Result: See the calculated missing angle value.

The Angle Calculator helps determine unknown angles in various geometric figures. It can solve for complementary (adds to 90°) and supplementary (adds to 180°) angles.

It also assists in finding internal angles of polygons (e.g., measuring the corner of a pentagon).
