Show that the points (a,b,c),(b,c,a),(c,a,b) are the vertices of an equilateral triangle.

Show that the points (a,b,c)(b,c,a) and (c,a,b) are the vertices of an equilateral triangle.

Show that A(a,b,c),B(b,c,a) and C(c,a,b) are the vertices of an equilateral triangle.

The points (a,b),(c,d), and ((kc+la)/(k+l),(kd+lb)/(k+l)) are (a) vertices of an equilateral triangle (b) vertices of an isosceles triangle (cc) vertices of a right-angled triangle (d) collinear

(a,b),(c,d),(e,f) are the vertices of an equilateral triangle.Then the orthocenter of the triangle is

If the points A(z),B(-z) and C(z+1) are vertices of an equilateral triangle then
