Question

which best describes the dimensions of a plane?
a plane has zero dimensions because it represents a location on the coordinate plane.
a plane has one dimension because it is made up of an infinite number of points.
a plane has two dimensions because it is a flat surface that has length and width but no depth.
a plane has three dimensions because it is made up of exactly three noncollinear points.

Explanation:

A point has zero dimensions. A line has one dimension (length). A plane is a flat surface. In geometry, a plane is defined as a two - dimensional figure. It has length and width (two dimensions) but no thickness (depth). Three non - collinear points determine a plane, but the plane itself is two - dimensional.

Answer:

A plane has two dimensions because it is a flat surface that has length and width but no depth.
