Triangle Calculator computes the area, angles, perimeter, angle bisector and the altitude of a triangle, as well as a diagram of the resulting triangle given three triangle side input parameters. Triangle vertices are usually named A, B and C. Triangle edges - a, b, c, where letter denotes opposite vertex. That is edge between A and B is named c, between A and C - b, between B and C - a. The formula includes as reference. For example, S - area of a triangle, which can be found from three known edge by using Hero's formula. All results are shown instantly and are copy-able. A triangle is a polygon that has three vertices. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges. A triangle is usually referred to by its vertices. Hence, a triangle with vertices a, b, and c is typically denoted as Δabc. Furthermore, triangles tend to be described based on the length of their sides, as well as their internal angles. For example, a triangle in which all three sides have equal lengths is called an equilateral triangle while a triangle in which two sides have equal lengths is called isosceles.
