In geometry a line:
- is straight (no bends),
- has no thickness, and
- extends in both directions without end (infinitely).
A line has no ends !
Play With It
Change the position of points A and B. Note that the line AB extends forever in both directions:
When it does have ends it is called a 'Line Segment'.
When it has just one end it is called a 'Ray'
This is Cool
Now play with this one ... point 'C' is made to always be an equal distance from point 'A' and 'B'. The result is a line (all the possible position of point 'C' make a line):
