Describing a flat surface in 3D space using a normal vector.
Equation of a Plane
The vector equation of a plane with normal vector $\vec{n}$, passing through a point with position vector $\vec{a}$:
$$(\vec{r} - \vec{a}) \cdot \vec{n} = 0$$Angle Between Two Planes
Found using the dot product of their respective normal vectors.
