The international standard ISO 216 defines sizes of paper sheets using the √ 2, in which the long side of a rectangular sheet of paper is the square root of two times the short side of the paper. Rectangles in this shape are rep-2. A rectangle (or parallelogram) is rep-n if its aspect ratio is √ n:1. An isosceles right triangle is also rep-2.
It is known for its elongated, rectangular shape, which presents a similarity to the straight razor, hence its name. The razor shell has been known to reach 23 centimetres (9 in) [ 4 ] in length. The dorsal margin is straight while the ventral margin is curved.
For example, in a polyhedron (3-dimensional polytope), a face is a facet, an edge is a ridge, and a vertex is a peak. Vertex figure: not itself an element of a polytope, but a diagram showing how the elements meet.
Chaetognaths are transparent or translucent dart-shaped animals covered by a cuticle. They range in length between 1.5 mm to 105 mm in the Antarctic species Pseudosagitta gazellae . [ 5 ] Body size, either between individuals in the same species or between different species, seems to increase with decreasing temperature. [ 5 ]
The most common example of a balbis is the capital letter 'H', the eighth letter in the ISO basic Latin alphabet. It can also be seen in, for example, rugby posts and old-fashioned television antenna. Another type of balbis is the rectangular balbis, that may be loosely described as a rectangle with one side missing.
The 12 pentominoes can form 18 different shapes, with 6 of them (the chiral pentominoes) being mirrored. Derived from the Greek word for ' 5 ', and " domino ", a pentomino (or 5-omino ) is a polyomino of order 5; that is, a polygon in the plane made of 5 equal-sized squares connected edge to edge.

Translating or rotating a one-sided polyomino does not change its shape. fixed polyominoes are distinct when none is a translation of another (pieces that can be neither flipped nor rotated). Translating a fixed polyomino will not change its shape. The following table shows the numbers of polyominoes of various types with n cells.
