Mathematical Lines
(Lines, Line Segments, Rays)


Mathematical lines, mathematical lines,
You’ll know them when you see them.
And you’ll know them every time.

Mathematical lines, geometric lines,
They’re easy to learn,
They’re easy to define.

Straight lines travel in both directions.
They travel to infinity.
Forever.

Line segments are a portion of a line.
A portion of a line with two end points.

Mathematical lines, mathematical lines,
You’ll know them when you see them.
And you’ll know them every time.

A line that starts from a point,
And travels to infinity
Forever.
That’s a ray.
It has a starting point.
It travels to infinity.

Mathematical lines, mathematical lines,
You’ll know them when you see them.
And you’ll know them every time.
