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
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.
A plane is a flat surface with no thickness
A flat, level surface is a plane.
A sphere
Theoretically, planes are flat surfaces that extend into infinity = no boundaries
