U+25BD "▽" White down-Pointing Triangle is a geometric symbol that represents an outlined downward-pointing triangle, often used in user interfaces, mathematical notation, and diagrams to indicate reduction, collapse, or a downward direction. It belongs to the Geometric Shapes block in Unicode and is frequently employed as a toggle control for expanding or collapsing sections of content, such as in tree views or dropdown menus.
