Question -
Answer -
Given:
The points A (3, 3, 3), B (0, 6, 3), C (1, 7, 7) and D (4, 4, 7)
We know that all sides of a square are equal.
By using the formula,
The distance between any two points (a, b, c) and (m, n, o) is given by,
It is clear that,
AB = BC = CD = AD
Quadrilateral formed by ABCD is a square. [Since all sides are equal]
Hence Proved.
