The Black Triangle Up symbol (▲) is one of the geometric shapes characters in the AllSymbols catalog. It comes from the Unicode Geometric Shapes block (U+25A0–U+25FF), which collects the squares, circles, triangles, diamonds, and bullseyes used as bullets, status dots, and pieces in chess and game notation.
Geometric shapes work as bullets, as status dots, and as direction indicators (the four cardinal triangles double as play/pause/forward/back controls in many UIs). Within one document, pick a single weight (small or large, solid or outline) and stick with it; mixing weights makes a list look noisy.
In Unicode, Black Triangle Up sits at code point U+25B2. Web pages reference it with the HTML numeric entity ▲; CSS rules reference it as a quoted hex escape (the four-digit code prefixed with a backslash); in JavaScript and most modern source-code contexts you can either paste the literal character or use a Unicode escape with the same hex digits.
If a shape carries meaning by color — for example, a red square for “danger” — pair it with a text label. Color and shape alone do not communicate to assistive technology, and the Unicode name (“BLACK SQUARE”) doesn’t carry your intended meaning.
If Black Triangle Up isn’t quite what you need, the Geometric Shapes page lists every related character on the site — including Black Circle and White Diamond. The related-symbols grid below also surfaces the closest sibling characters.
