Point, line, ray, line segment
A kite string, a ruler edge, a torch beam. Look at their ends.

Step 1 of 4
- A point — one exact spot, no length at all.
- A line — no fixed end. Arrows both ways.
- A ray — one fixed end, one open end.
- A line segment — two fixed ends.
The rule
Four shapes with different ends.
- Point — one exact spot. No length.
- Line — no end on either side. Arrows show it.
- Ray — one fixed end (a dot), one open end (an arrow).
- Line segment — two fixed ends. A ruler draws one.
Example
A torch beam starts at the torch and has no far end. The beam has one fixed end and one open end. So it is a ray.
A kite string is tied at both ends. The string has two fixed ends. So it is a line segment.
