Pythagorean theorem is the base for the right triangle calculator. Try conversion angle units angle degrees, minutes, seconds, radians, grads. Most natural application of trigonometry and trigonometric functions is a calculation of the triangles. Common and less common calculations of different types of triangles offers our triangle calculator. Word trigonometry comes from Greek and literally means triangle calculation.
