Question 860344: what is the definition or meaning of a plane?
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! A plane has infinite length, infinite width, and zero height (or thickness).
However, we need a notion for defining a plane in three dimensional space.
So, here we go.
A point is represented by 1 letter. A plane is represented by three points, or three letters. The points must be non-collinear, or not on the same line, because in three dimensions, there could be multiple planes that have the same three non-collinear points by rotating one plane around the line.
