The median of a triangle is defined as the length of a line segment that extends from a vertex of the triangle to the midpoint of the opposing side. A triangle can have three medians, all of which will intersect at the centroid the arithmetic mean position of all the points in the triangle of the triangle.
Refer to the figure provided below for clarification. The medians of the triangle are represented by the line segments m a , m b , and m c. The length of each median can be calculated as follows:. The inradius is the radius of the largest circle that will fit inside the given polygon, in this case, a triangle. The inradius is perpendicular to each side of the polygon. In a triangle, the inradius can be determined by constructing two angle bisectors to determine the incenter of the triangle.
The inradius is the perpendicular distance between the incenter and one of the sides of the triangle. Any side of the triangle can be used as long as the perpendicular distance between the side and the incenter is determined, since the incenter, by definition, is equidistant from each side of the triangle. For the purposes of this calculator, the inradius is calculated using the area Area and semiperimeter s of the triangle along with the following formulas:.
The circumradius is defined as the radius of a circle that passes through all the vertices of a polygon, in this case, a triangle.
