# U+1F53DDown-Pointing Small Red Triangle

U+1F53D was added in Unicode version 6.0 in 2010. It belongs to the block U+1F300 to U+1F5FF Miscellaneous Symbols and Pictographs in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

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 Variation Selector-15: 🔽︎ See the Emojipedia for more details on this character’s emoji properties.

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 $A,$ $B,$ and $C$ is denoted $△ABC.$ 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 $a$ 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 $\angle BCA.$
