The Parallel To symbol (∥) is a mathematical operator primarily used in geometry to indicate that two lines or planes run perfectly alongside each other without ever intersecting. While it looks similar to typing two standard pipe characters (||), this specific Unicode symbol is properly spaced and weighted for mathematical equations. You'll frequently spot it in textbooks, technical documentation, or when formatting precise math formulas online.

How to Type

Windows
Alt+8741 or Win+. then search "parallel"
