Mutual arrangement of planes

This calculator is designed for determining the mutual arrangement of two planes in space online.

Two planes can have three variants of mutual arrangement relative to each other. Firstly, the planes can be parallel. Secondly, they can be perpendicular. In this case, the angle between the planes is 90 degrees. Thirdly, the planes can intersect, forming two acute and two obtuse angles.

Thus, with the help of this calculator, the following is determined: whether the planes intersect or not, and if they intersect, whether they are perpendicular.

To answer the question of the mutual arrangement of planes, it is necessary to enter the equations of the given planes into the calculator and press the button «Calculate».

Enter the equations of the planes: x + y + z + = 0 and x + y + z + = 0

The planes are mutually perpendicular. The planes are parallel. The planes coincide. Intersect, but are not perpendicular.
