Show that the points `(p,q,r),(q,r,p)` and `(r,p,q)` are the vertices of an equilateral triangle.

Text Solution

Verified by Experts

The correct Answer is:
`AB^(2)=BC^(2)=CA^(2)` i.e. `bar(AB)=bar(BC)=bar(CA)` i.e. three sides of the triangle ABC are equal; hence the triangle ABC is an equilateral triangle.
