Planes in Algebra

Planes extend infinitely on the x-axis

Planes extend infinitely on the y-axis

Arrows designate the truth that it extends infinitely along the x-axis and the y-axis on the number lines’ ends

Intersecting Planes

Two planes can be related in three ways, in a three-dimensional space.

1. They can be parallel to each other
2. They can be identical
3. They can intersect each other
