	Intersection of Planes

The smaller one, $\varphi\in[0,\pi/2]$ , of the two angles between two planes with normal vectors $\vec{n}_i$ is uniquely determined by

$\displaystyle \cos(\varphi) = \frac{\vert\vec{n}_1\cdot \vec{n}_2\vert} {\vert\vec{n}_1\vert\vert \vec{n}_2\vert}$

and

$\displaystyle \vec{n}_1\times\vec{n}_2$

is the direction of the line of intersection.
