What undefined geometric term is described as two dimensional set of points that has no beginning or end

A Plane

Step-by-step explanation:

A plane is defined as a flat 2-dimensional surface that extends infinitely far.It is undefined because it has no beginning or an end.It continues to extend indefinitely.It is two-dimensional to mean it has a length or width.An example of a plane is the surface of a table.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
