Q4 of 84 Page 28

If the extremities of the diagonal of a square are (1, -2, 3) and (2, -3, 5), then the length of the side is

Given: Extremities of the diagonal of a square are P(1, -2, 3) and Q(2, -3, 5)


To find: Length of the diagonal


Formula used:


The distance between any two points (a, b, c) and (m, n, o) is given by,



Therefore,


Distance between P(1, -2, 3) and Q(2, -3, 5) is






Hence, Length of the diagonal is units
