Definition:

A triangle is a polygon formed by the union of three segments, where the points of intersection are non-collinear points. Points of intersection are called vertexes, and the segments are referred to as sides.

The scalene triangle is the triangle which has all sides of different lengths.

The area of a triangle is equal to one half of the sum of base and height.

Computing relationship:

where:

a — the base of triangle;

h — the height of triangle.
