A two-dimensional figure, also called a plane or planar figure, is a set of line segments or sides and curve segments or arcs, all lying in a single plane. The sides and arcs are called the edges of the figure. The edges are one-dimensional, but they lie in the plane, which is two-dimensional. The triangle, the pentagon, the hexagon and the circle are just a few plane figures. Prisms and pyramids, for instance, are three-dimension figures.

A line
It could be a Euclidean plane.
A line is related to a surface as a point to a plane. In geometry, a point has no dimensions and defines a location in space, while a plane is a two-dimensional surface that extends infinitely in all directions. Similarly, a line is a one-dimensional figure that extends infinitely in two opposite directions, while a surface is a two-dimensional figure that extends infinitely in all directions.
The term you are looking for is "line." In geometry, a line is a one-dimensional figure that extends infinitely in both directions. It is composed of an infinite number of points and has no endpoints.
A plane figure
The best way to measure thickness is to use an ultrasonic transducer. You use the back reflection to figure out the thickness.
No. A plane extends to the ends of the universe.
