Which undefined geometric term is described as an infinite set of points that has length but not width?

The undefined geometric term is described as an infinite set of points that has length but not width is:

Line.

Step-by-step explanation:

There are three undefined geometric terms:

Point, Line and Plane.

Hence, the undefined geometric term is described as an infinite set of points that has length but not width is LINE.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

3 is greater then both of those numbers
