Upper Right Triangle

The Upper Right Triangle at U+25F9 is a printable geometric symbol made from the upper-right half of a square-like area. It belongs to the Geometric Shapes block and functions as a small directional or sectional marker rather than as a letter, punctuation mark, or standard mathematical operator. In practice it is used most often in charts, legends, interface sketches, and compact diagrams where a designer needs to distinguish one corner, quadrant, or diagonal half from related shapes. For example, a table key might use ◹ to mark an item assigned to the upper-right quadrant, or a schematic might pair it with other corner triangles to show orientation. It can also appear in custom data visualizations, board-game notation, map keys, or accessibility-unfriendly icon sets as a terse visual label. Unlike common arrows or filled triangles, ◹ has no broadly agreed meaning by itself, so its interpretation normally comes from a legend or surrounding explanation. Its exact proportions and fill style can vary by font, which matters when it is being aligned with the other quarter-triangle symbols.
