Theory. Angle between two planes
The angle between two planes is equal to a angle between their normal vectors.
If A1x + B1y + C1z + D1 = 0 and A2x + B2y + C2z + D2 = 0 are a plane equations, then angle between planes can be found using the following formula
|cos α =|||A1·A2 + B1·B2 + C1·C2||
|√A12 + B12 + C12 √A22 + B22 + C22|
