# Geometry symbols - Maths

The symbols that denote the properties and configurations of geometric shapes are known as geometry symbols.

Mathematics deals with two basic types of geometry-

1. Plane geometry: - For geometric shapes like triangles, circles, and lines.
2. Solid geometry: -For three-dimensional geometric shapes like spheres, cubes, and cuboids.

## List of geometric shapes and their symbols

A student has to make sure to memorize these symbols to diversify their knowledge. These symbols come in handy in every field where mathematics is dominant.

1. Various geometric symbols are used in engineering for defining and communicating various shapes and figures, such as
 Type of control Geometric characteristics Form Straightness Form Flatness Form Circularity Form Cylindricity Location Symmetry[f][g] Location Position Location Concentricity[f] Orientation Perpendicularity Profile Profile of a line Orientation Angularity Orientation Parallelism Profile Profile of a surface Run-out Circular run-out Run-out Total run-out
2. Production industrialists use it to mark the degree of precision and accuracy during manufacturing machines and products.
3. It is used by Indian Standard Organisation (ISO) to mark basic standards of products so that everyone can understand them. ISO marks are universal.
4. They reduce the space needed for writing long descriptions. Usage of geometric symbols takes less space and is clearer to understand and read.
