Plane: A flat surface with no thickness
When we draw something on a flat piece of paper we are drawing on a plane ...
... except that the paper itself is not a plane, because it has thickness! And it should extend forever, too.
So the very top of a perfect piece of paper
that goes on forever is the right idea!
Also, the top of a table, the floor and a whiteboard are all like a plane.
Line: A series of points on a plane that go on forever
Segment: A part of a line with two endpoints
Point: A location in space on a plane
Ray: A part of a line but with only one endpoint and goes on forever in one direction
Vertex: The point at which two lines intersect
Angle: Two rays with the same endpoint
Congruent: With equal sides and angles
