a plane
yes, a plane is a falt surface, because infinite flat surface is a plane.
no. an angle is a pointed surface that has 2 boundaries.
A plane is a flat surface
A flat surface that extends forever is a plane

A plane the desert
A flat surface, like a sheet of paper, with no edges (ie: it goes on and on and on and on....) or boundaries. What you're describing is a 2 dimensional plane. No, not plane like an airplane. A plane is simply a flat "sheet" that goes on forever in 2 dimensions: left/right (wide) and up/down (tall).

No. A flat surface which is horizontal is not an inclined plane.
An endless flat surface, also known as an infinite plane, is a theoretical concept in geometry that extends indefinitely in all directions. It has the properties of being flat, meaning that at any point on the plane, the surface is perfectly level with no curvature. In mathematics, an infinite plane is often used as a simplified model for understanding concepts such as coordinate systems, vectors, and geometric shapes.
A sphere
A plane is a flat surface with no thickness
A flat, level surface is a plane.
Theoretically, planes are flat surfaces that extend into infinity = no boundaries
