Angle between planes
The angle between the planes is the angle between the perpendiculars to their intersection line drawn in these planes. It is worth noting that the intersecting planes form two angles. The other angle can be found as follows: φ’=180-φ. To calculate the angle between the planes, enter the elements of the equation of the planes into the cells and click on the “Calculate” button..
