A triangle has three vertices. A triangle consists of three lines, and the location where one line endpoint meets another line endpoint is called a vertex. A square consists of four vertices, while an octagon contains ei... More »

The area of a triangle can be calculated from its vertices by using a formula to find the distances between them. This allows for the calculation of the area of a parallelogram with the same base and height as the triang... More »

A cylinder has zero vertices. A cylinder does not have a vertex because there is no point where two lines meet. This is because a cylinder, unlike a prism, has circular faces; there is no corner where two straight lines ... More »

A polygon is identified based on the number of its sides and vertices. Polygons are made of straight lines, called edges or sides, that meet in corners to form a closed circuit. The least number of sides needed to form a... More »

A line segment that connects two non-consecutive vertices is a diagonal in a polygon. Every quadrilateral has two of these diagonals, which separate it into triangles. More »

The polygon with 1,000 sides, 1,000 vertices and 1,000 angles is called a chiliagon or a 1,000-gon. The term "chiliagon," with a Greek-derived prefix meaning “thousand,” is a proposed name for the 1,000-sided, two-dimens... More »
