Triangle calculator SSA

Please enter two sides and a non-included angle

The calculator solves the triangle given by two sides and a non-included angle between them (abbreviation SSA side-side-angle). The picture shows a typical case of solving a triangle when thee are given two sides a, b and one non-included angle (opposing angle) β. Uses quadratic equation (can be zero, one or two solutions), then Heron's formula and trigonometric functions to calculate area and other properties of a given triangle.
