Which symbol represents a diode?

In schematics, components are drawn with standardized symbols that convey function at a glance. A diode has a distinctive symbol: a triangle meeting a vertical bar, with current traditionally flowing from the triangle side (anode) toward the bar (cathode) when forward-biased. This shape is unique to diodes and distinguishes it from other parts. The resistor symbol is a zig-zag line (or a rectangle in some drawings), and the capacitor symbol is two parallel lines. So the symbol that represents a diode is the one that shows the triangle contacting the line—the diode symbol. The term "Diode" describes the component itself, not its schematic representation.
