Find the centroid of tetrahedron with vertices K(5, -7, 0), L(1, 5, 3), M(4, -6, 3), N(6, -4, 2) ?

To find the centroid of a tetrahedron with given vertices, you can use the formula for the centroid (G) of a tetrahedron defined by its vertices A(x1, y1, z1), B(x2, y2, z2), C(x3, y3, z3), and D(x4, y4, z4). The coordinates of the centroid are calculated as follows:

Centroid Formula

The centroid G is given by:

• Gx = (x1 + x2 + x3 + x4) / 4
• Gy = (y1 + y2 + y3 + y4) / 4
• Gz = (z1 + z2 + z3 + z4) / 4

Applying the Formula

For the vertices K(5, -7, 0), L(1, 5, 3), M(4, -6, 3), and N(6, -4, 2), we can substitute the coordinates into the formula:

• Gx = (5 + 1 + 4 + 6) / 4 = 16 / 4 = 4
• Gy = (-7 + 5 - 6 - 4) / 4 = -12 / 4 = -3
• Gz = (0 + 3 + 3 + 2) / 4 = 8 / 4 = 2

Result

The coordinates of the centroid G of the tetrahedron are:

G(4, -3, 2)
