Perpendicular Symbol Meaning
⟂ (Unicode name: PERPENDICULAR, code point U+27C2) is the perpendicular sign. Most commonly, it indicates that two lines, segments, or directions are perpendicular—meeting at a 90° angle. You’ll see it in geometry, technical drawings, and explanations of orthogonal coordinate axes. In some contexts, it can also be used as a compact notation for “perpendicular” without spelling out the word, such as labeling a diagram or annotating a graph. When you need a clear visual cue for right angles in text, ⟂ is a concise alternative to writing “is perpendicular to.”
Common uses
- •Labeling right angles in geometry notes and diagrams
- •Indicating perpendicular line relationships in technical explanations
- •Marking orthogonal axes or coordinate directions in math writing
- •Adding a quick annotation in engineering or drafting documentation
- •Using as a typographic symbol to describe perpendicular constraints in design specs
