A Coggle Diagram about 2.1
(Through any two points, there is exactly one line.
(Through any three noncollinear points, there is exactly one plane.
(A line contains at least two points.
(A plane contains at least three noncollinear points.
(If two points lie in a plane, then the entire line containing those points lies in that plane.
(If two lines intersect, then their intersection is exactly one point.
(If two planes intersect, then their intersection is a line.
