Question

What is a $3$-d plane called?

Answer 1

Cartesian coordinate system-3d plane:

A $3$-d or three-dimensional plane is called a hyperplane.

• $3$-d plane contains three axes that intersect at the origin.
• The three axes $x$-axis, $y$-axis, and $z$-axis are mutually perpendicular to each other.
• The point in the plane is in the form $\left(x,y,z\right)$.

Hence, 3-d plane called as hyperplane.
