Category:Inclinations between Planes

This category contains results about Inclinations between Planes.
Definitions specific to this category can be found in Definitions/Inclinations between Planes.

Definition 1

The inclination between two intersecting planes is the smaller of the dihedral angles between them.

Definition 2

Let $\PP_1$ and $\PP_2$ be planes.

Let $\mathbf n_1$ and $\mathbf n_2$ be normal vectors to $\PP_1$ and $\PP_2$ respectively, oriented such that the angle $\theta$ between them is such that:

$0 \le \theta \le \dfrac \pi 2$

that is:

$0 \degrees \le \theta \le 90 \degrees$

The inclination between $\PP_1$ and $\PP_2$ is defined as that $\theta$.
