If origin is the ortho-center of an equilateral triangle whose vertices are \overline{a}, \overline{b}, \overline{c} then

\overline{a}+\overline{b}=\overline{c}

\overline{a}+\overline{b}=-\overline{c}

|\overline{a}|^{2}=|\overline{b}|^{2}=∣ \overline{c}^{2}

\overline{a}=\overline{b}=\overline{c}
