In geometry, points and linesform the foundation of more complex geometrical figures such as triangles, circles, quadrilaterals and polygons. The following table documents some of the most notable symbols related to these — along with each symbol’s meaning and example.
An angleessentially corresponds to an “opening” of a geometrical figure, whose quantification leads to much development in geometry and trigonometry. The following table documents some of the most notable symbols related to angles — along with each symbol’s meaning and example.
A circle can be thought of as a set of all points equidistant to a given point, and often plays a crucial role in the development of Euclidean geometryand trigonometry. The following table documents some of the most notable symbols related to circle — along their respective meaning and example.
In trigonometry, many functions are used to relate angles within a right triangle to its various lengths or ratios. The following table documents some of the most common functions in this category — along with their respective usage and example.
In elementary geometry, much of the study revolves around the analysis of polygons, polyhedra and other 3-dimensional figures. The following table documents some of the most notable symbols in these categories — along with each symbol’s respective meaning and usage. The following figures illustrate the 5 platonic solids(regular, convex polyhedra), ...
Here are the most common geometrical symbols: The angle formed by ABC is 45 degrees. 360 degrees (a full rotation!) Is really saying: "In triangle ABC, the angle BAC is a right angle" For angles the central letter is where the angle is. The point "B" is where the angle is.

Either plus or minus depending on the situation. If y= [+|-]x then x is either positive or negative depending on the situation. y= [+|-]x y equals either +x or -x depending on the scenario.
For most symbols, the entry name is the corresponding Unicode symbol. So, for searching the entry of a symbol, it suffices to type or copy the Unicode symbol into the search textbox. Similarly, when possible, the entry name of a symbol is also an anchor, which allows linking easily from another Wikipedia article.
