The constant ratio by which all distances are increased (or decreased) in a similarity. A similarity with ratio of magnification equal to 1 is called an isometry.

The plane spanned by the tangent vector T and binormal vector B.

The regular decagon is constructible 10-sided regular polygon with Schläfli symbol {10}. The inradius r, circumradius R, and area can be computed directly from the formulas ...

Consider the plane figure obtained by drawing each diagonal in a regular polygon. If each point of intersection is associated with a node and diagonals are split ar each ...

A triangle center is regular iff there is a triangle center function which is a polynomial in Delta, a, b, and c (where Delta is the area of the triangle) such that the ...

A polyhedron with extra square faces, given by the Schläfli symbol r{p; q}.

A beautiful class of polyhedra composed of rhombic faces discovered accidentally by R. Towle while attempting to develop a function to create a rhombic hexahedron from a ...

The dual polyhedron of the rhombicosahedron U_(56) and Wenninger dual W_(96).

A parallelogram in which angles are oblique and adjacent sides are of unequal length.

A three-dimensional coordinate system in which the axes satisfy the right-hand rule.
