Method
Formula, when it applies, and when it does not
Resolve hypotenuse, area, and acute angles from two perpendicular legs in a clearly diagrammed triangle.
c = √(a² + b²); A = ab / 2; α = tan⁻¹(b/a)
When
- Two perpendicular legs
- Euclidean plane geometry
- Positive side lengths
Don’t
- This uses a flat Euclidean right triangle. It does not infer dimensions from a drawing, field measurement, tolerance, or a non-perpendicular geometry.
