Leave AB alone a line section whose midpoint is P (a, b).
Leave the directions of An and B alone (0, y) and (x, 0) individually.
\[\mathbf{a}\text{ }\left( \mathbf{y}\text{ }\text{ }\mathbf{2b} \right)\text{ }=\text{ }-\text{ }\mathbf{bx}\]
\[\mathbf{ay}\text{ }\text{ }\mathbf{2ab}\text{ }=\text{ }-\text{ }\mathbf{bx}\]
\[\mathbf{bx}\text{ }+\text{ }\mathbf{ay}\text{ }=\text{ }\mathbf{2ab}\]
