In computer graphics, a triangle strip is a subset of triangles in a triangle mesh with shared vertices, and is a more memory-efficient method of storing information about the mesh. They are more efficient than un-indexed lists of triangles, but usually equally fast or slower than indexed triangle lists.
Triangles are greedily added to a strip until no triangle is available that can be appended to the strip; a new strip will be started in this case. When choosing a triangle for starting or continuing a triangle strip, the selection is based on a triangle's degree (i.e. the number of triangles adjacent to it), with smaller degrees being preferred.
One way of sharing vertex data between triangles is the triangle strip. With strips of triangles each triangle shares one complete edge with one neighbour and another with the next. Another way is the triangle fan which is a set of connected triangles sharing one central vertex.
A strip of paper can form a flattened Möbius strip in the plane by folding it at angles so that its center line lies along an equilateral triangle, and attaching the ends. The shortest strip for which this is possible consists of three equilateral triangles, folded at the edges where two triangles meet.
Degenerate triangles Zero area triangle primitives placed in a triangle strip between actual primitives, to allow many parts of a triangle mesh to be rendered in a single drawcall. These are rejected by the triangle setup unit. [11] Delaunay triangulation A method for generating an efficient triangulating between a set of vertices in a plane ...

The two yellow triangles on the ends will end up taped together. The red and blue arcs are seen as full circles on the inside of one side or the other when folded. A hexaflexagon with three faces is the simplest of the hexaflexagons to make and to manage, and is made from a single strip of paper, divided into nine equilateral triangles.
