A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments , half-lines , or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain ...
The playing pieces in the game are known as "cones" (or "men" in the UK) because of their cone shape. This allows them to be stacked on top of one another in unlimited numbers. Each player starts off with four cones, and whenever one player lands on the space occupied by the cone of another, this player captures the opponent's cone.
The carnivorous plant Nepenthes deaniana has pitcher elements that are obconic in shape to capture insects. [2] The hypanthium of the western USA plant Heuchera rubescens has one subspecies with an obconic structure, while several other subspecies have alternative hypantium geometries, so that the obconic characteristic is a subspecies determinant and diagnostic.

Cone (hill), a hill in the shape of a cone which may or may not be volcanic in origin; Dirt cone, a feature of a glacier or snow patch, in which dirt forms a coating insulating the ice below; Parasitic cone (or satellite cone), a geographical feature found around a volcano
The cone over two points {0, 1} is a "V" shape with endpoints at {0} and {1}. The cone over a closed interval I of the real line is a filled-in triangle (with one of the edges being I), otherwise known as a 2-simplex (see the final example). The cone over a polygon P is a pyramid with base P. The cone over a disk is the solid cone of classical ...

In geometry, a bicone or dicone (from Latin: bi-, and Greek: di-, both meaning "two") is the three-dimensional surface of revolution of a rhombus around one of its axes of symmetry.
This shape may be projected into 3-dimensional space in various ways. If projected onto the xyz hyperplane, its image is a ball. If projected onto the xyw, xzw, or yzw hyperplanes, its image is a solid cone. If projected onto an oblique hyperplane, its image is either an ellipsoid or a solid cone with an ellipsoidal base (resembling an ice ...
