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:

Ax + By + Cz + D = 0

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

I made this calculator to calculate the equation of each plane from three points, and then the angle between them:
