Dihedral Angle Calculator


A dihedral angle is the angle between two planes.

To calculate this angle, you can follow these steps:

1. Calculate the equation for each plane. It will be in the form:

plane formula

2. Then, knowing the equation of the two planes, you can calculate the dihedral angle:
