U+1F53D DownPointing Small Red Triangle
U+1F53D 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 character is also known as play arrow down.
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+1F53D forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “downwards button” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: arrow, button, down.
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 zerodimensional points while the sides connecting them, also called edges, are onedimensional line segments. The triangle's interior is a twodimensional 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 noncollinear, determine a unique triangle situated within a unique flat plane. More generally, several points in Euclidean space of arbitrary dimension determine a simplex.
In nonEuclidean 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 twodimensional 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 circulararc sides. This article is about straightsided triangles in Euclidean geometry, except where otherwise noted.
A triangle with vertices $A,$ $B,$ and $C$ is denoted $\u25b3ABC.$ In describing metrical relations within a triangle, it is common to represent the length of the edge opposite each vertex using a lowercase letter, letting $a$ be the length of the edge $BC,$ $b$ the length of $CA,$ and $c$ the length of $AB$; and to represent the angle measure at each corner using a Greek letter, letting $\alpha $ be the measure of angle $\angle CAB,$ $\beta $ the measure of $\angle ABC,$ and $\gamma $ the measure of $\angle BCA.$
