In ordinary geometry (as opposed to affine geometry), a plane MUST consist of an infinite set of points.
yes, a plane is a falt surface, because infinite flat surface is a plane.
The plane that geometry refers to is not an airplane. A plane is a two-dimensional group of points that goes on infinitely in all directions; made up of infinite line. For example, a rectangle is a plane.
An infinite number in a Euclidean plane - which is the "normmal" plane. Some selected numbers in the finite or affine planes (but you need to be studying projective geometry to come across these).
Two dimensional geometry is called "plane geometry" meaning that it occurs on a single surface or plane. The objects used in plane geometry are called plane figures.
