Definition
Perpendicularity is the state or quality of being perpendicular, which means forming a right angle (90 degrees). It describes the relationship between two lines, planes, or surfaces that intersect at a right angle. Think of the corner of a square 🟫 or the intersection of a wall and the floor. Perpendicularity emphasizes precision, stability, and right angles. It is fundamental in geometry, architecture, and engineering. It's a key element in structural integrity.
