Two vertices of an equilateral triangle are origin and (4, 0). What is the area of the triangle ?

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

If vec(a), vec(b) and vec(c ) are the position vectors of the vertices of an equilateral triangle whose orthocenter is at the origin, and then which one of the following is correct?

If vec a,vec b,vec c are the position vectors of the vertices of an equilateral triangle whose orthocenter is at the origin,then
