The center of gravity of the triangle is the intersection of the three lines of the triangle. When the geometry is a homogeneous object, the center of gravity coincides with the centroid.
In a plane rectangular coordinate system, the coordinates of the center of gravity are the arithmetic mean of the coordinates of the vertices.
That is, its coordinates are ((X1+X2+X3)/3, (Y1+Y2+Y3)/3;
Spatial Cartesian Coordinate System - abscissa: (X1+X2+X3)/3, ordinate: (Y1+Y2+Y3)/3, vertical coordinate: (Z1+Z2+Z3)/3
X1: 2；Y1: 4
X2: 3；Y2: 5
X3: 2；Y3: 1
Click "calculate" to output the result
Center of gravity (g): 7/3, 10/3
