U+1F53B Down-Pointing Red Triangle
U+1F53B was added in Unicode version 6.0 in 2010. It belongs to the block
This character is a Other Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+1F53B forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “red triangle pointed down” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: down, geometric, red.
This character is designated as an emoji. It will be rendered as colorful emoji on conforming platforms. To reduce it to a monochrome character, you can combine it with
The Wikipedia has the following information about this codepoint:
A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called vertices, are zero-dimensional points while the sides connecting them, also called edges, are one-dimensional line segments. The triangle's interior is a two-dimensional region. Sometimes an arbitrary edge is chosen to be the base, in which case the opposite vertex is called the apex.
In Euclidean geometry, any two points determine a unique line segment situated within a unique straight line, and any three points, when non-collinear, determine a unique triangle situated within a unique flat plane. More generally, several points in Euclidean space of arbitrary dimension determine a simplex.
In non-Euclidean geometries three straight segments also determine a triangle, for instance a spherical triangle or hyperbolic triangle. A geodesic triangle is a region of a general two-dimensional surface enclosed by three sides which are straight relative to the surface. A curvilinear triangle is a shape with three curved sides, for instance a circular triangle with circular-arc sides. This article is about straight-sided triangles in Euclidean geometry, except where otherwise noted.
A triangle with vertices and is denoted In describing metrical relations within a triangle, it is common to represent the length of the edge opposite each vertex using a lower-case letter, letting be the length of the edge the length of and the length of ; and to represent the angle measure at each corner using a Greek letter, letting be the measure of angle the measure of and the measure of
