It is a noninstantiable class but has a number of properties, described in the following list, that are common to all geometry values created from any of the Geometry subclasses. Geometry Properties A geometry value has the following properties: Its ...
https://dev.mysql.com/gis-geometry-class-hierarchy.html
The geometry classes define a hierarchy as follows: Geometry (noninstantiable) Point (instantiable) Curve (noninstantiable) LineString (instantiable) Line LinearRing Surface (noninstantiable) Polygon (instantiable) GeometryCollection (instantiable) ...
https://dev.mysql.com/geometry-well-formedness-validity.html
For geometry values, MySQL distinguishes between the concepts of syntactically well-formed and geometrically valid. Spatial import functions that parse WKT or WKB values raise an error for attempts to create a geometry that is not syntactically ...
https://dev.mysql.com/opengis-geometry-model.html
The set of geometry types proposed by OGC's SQL with Geometry Types environment is based on the OpenGIS Geometry Model. In this model, each geometric object has the following general properties: It is associated with a spatial reference system, ...

The following table lists each spatial function and provides a short description of each one.
https://dev.mysql.com/spatial-operator-functions.html
OpenGIS proposes a number of functions that can produce geometries. These functions support all argument type combinations except those that are inapplicable according to the Open Geospatial Consortium specification. Unless otherwise specified, ...
https://dev.mysql.com/gis-format-conversion-functions.html
MySQL supports the functions listed in this section for converting geometry values from internal geometry format to WKT or WKB format, or for swapping the order of X and Y coordinates. There are also functions to convert a string from WKT or WKB ...
https://dev.mysql.com/gis-mysql-specific-functions.html
MySQL provides a set of useful nonstandard functions for creating geometry values. The functions described in this section are MySQL extensions to the OpenGIS specification. These functions produce geometry objects from either WKB values or ...
