straight lines

Geometry's simplest segments

Straight lines are the shortest paths between two points, extending infinitely in both directions without curving or bending.

In geometry, they're fundamental—defined by any two points.

The phrase often emphasizes directness or simplicity: The architect preferred straight lines to curves.

Draw a straight line from A to B.
