AI overview

Perpendicularity describes the relationship between two lines or segments that meet at a 90-degree angle, with each of the angles formed at their intersection being exactly 90 degrees. This concept matters because perpendicular lines are fundamental to measuring distances, constructing right angles, and establishing coordinate systems used across mathematics, engineering, and everyday spatial navigation.
