Lists of shapes cover different types of geometric shape and related topics. They include mathematics topics and other lists of shapes, such as shapes used by drawing ...
Having a constant diameter, measured at varying angles around the shape, is often considered to be a simple measurement of roundness.This is misleading. [3]Although constant diameter is a necessary condition for roundness, it is not a sufficient condition for roundness: shapes exist that have constant diameter but are far from round.

This is a list of two-dimensional geometric shapes in Euclidean and other geometries. For mathematical objects in more dimensions, see list of mathematical shapes. For a broader scope, see list of shapes.
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. The distance between any point of the circle and the centre is called the radius. The length of a line segment connecting two points on the circle and passing through the centre is called the diameter.
Schematic representation of difference in grain shape. Two parameters are shown: sphericity (vertical) and rounding (horizontal). Rounding, roundness or angularity are terms used to describe the shape of the corners on a particle (or clast) of sediment. [1] Such a particle may be a grain of sand, a pebble, cobble or boulder.

Squircle centred on the origin (a = b = 0) with minor radius r = 1: x 4 + y 4 = 1A squircle is a shape intermediate between a square and a circle.There are at least two definitions of "squircle" in use, one based on the superellipse, the other arising from work in optics.
