Triangle from Coordinates

From the vertex coordinates this calculator finds the area, medians, centroid, orthocenter, incenter and circumcenter, checks the position of a point and draws the triangle.

Main formulas

G = (^{x_A + x_B + x_C}/₃, ^{y_A + y_B + y_C}/₃)

H = A + B + C − 2O

Example. A(0, 0), B(6, 0), C(2, 4): the area is 12, G = (8/3, 4/3), O = (3, 1), H = (2, 2).
