P (0, 7, -7), Q (1, 4, -5) and R (-1, 10, -9)
Given:
The points P (0, 7, -7), Q (1, 4, -5) and R (-1, 10, -9)
Points P, Q and R are collinear if PQ + QR = PR or PQ + PR = QR or PR + QR = PQ
By using the formula,
Distance between any two points (a, b, c) and (m, n, o) is given
The points P, Q and R are collinear.

The mid-points of the sides of a triangle ABC are given by (-2, 3, 5), (4, -1, 7) and (6, 5, 3). Find the coordinates of A, B and C.
If the points A(3, 2, -4), B(9, 8, -10) and C(5, 4, -6) are collinear, find the ratio in which C divided AB.
Find the ratio in which the line segment joining the points (2, -1, 3) and (-1, 2, 1) is divided by the plane x + y + z = 5.
Find the ratio in which the line joining (2, 4, 5) and (3, 5, 4) is divided by the yz-plane.
