Question -
Answer -
Given:
The points (1, 2, 3), (2, 3, 1) and (3, 1, 2)
An equilateral triangle is a triangle whose all sides are equal.
So let us prove AB = BC = AC
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 = AC
Δ ABC is a equilateral triangle
Hence Proved.
