About the Triangle Calculator
The Triangle Calculator solves for all sides, angles, area, and perimeter of a triangle given different input combinations. Use SSS (three sides), SAS (two sides and included angle), or ASA (two angles and included side) methods.
How to Use This Calculator
- Select your input method (SSS, SAS, or ASA)
- Enter the known values for sides and/or angles
- View all calculated properties of the triangle
- See the triangle type classification
Triangle Solution Methods
- SSS (Side-Side-Side): All three sides known
- SAS (Side-Angle-Side): Two sides and the included angle
- ASA (Angle-Side-Angle): Two angles and the included side
