Geometry Help

Enter 3 values including at least one side. We use the Law of Sines and Law of Cosines to find the missing variables. If the inputs don't form a valid triangle, we'll alert you immediately.

Key Concepts
  • SSS: Three sides known.
  • SAS: Two sides and included angle.
  • ASA: Two angles and included side.
Internal Sum

The sum of all internal angles in any Euclidean triangle must be exactly 180°. If your inputs exceed this, the triangle is invalid.

Expert Math Tip

When using this tool for land surveying, remember that the "Area" result is in square units relative to your side inputs. If sides are in feet, area is in square feet!
