Right Triangle Calculator

Solve any right triangle from two known values — sides or angles — for shop-floor layout and geometry.

Most shop geometry reduces to a right triangle. From any two known sides or one side and one angle, the rest follow from the Pythagorean theorem and basic trig ratios.

Formula: a² + b² = c²; sin θ = opp/hyp, cos θ = adj/hyp, tan θ = opp/adj

Worked Example

  1. Legs a = 3, b = 4 → hypotenuse c = √(3² + 4²) = 5.
  2. Angle at a = atan(4/3) ≈ 53.13°.
