A plane drawn in green with four points on the plane labeled
\(Q\text{,}\) \(P_0\text{,}\) \(P_1\text{,}\) and
\(P_2\text{.}\) Blue arrows are drawn along the plane from
\(P_0\) to each of
\(Q\text{,}\) \(P_1\text{,}\) and
\(P_2\text{.}\) A red arrow that his perpendicular to the green plane is drawn, starting at the point
\(P_0\) and is labeled
\(\vec{n}\text{.}\)
