Stop signs are octagons. An octagon is a shape that has eight sides, whereas a hexagon only has six sides.
Know MoreIn North America, you will find stop signs to assist right of way for pedestrians and traffic. They are used in areas of towns and cities that are not large enough to warrant the use of traffic lights. Stop signs can be used alone or as part of a three-way or four-way stop.
Both hexagons and octagons can be irregular or regular. A regular shape has sides that are all equal in length. An irregular shape has sides of different lengths.

Translations move every point within the shape the same distance and preserve the geometrical properties of the original shape.
Full Answer >A tessellation is a pattern of geometric shapes that can completely cover a surface without the shapes overlapping one another or leaving any gaps. Tessellations may also be called tilings, as the individual shapes in the pattern resemble tiles.
Full Answer >A geometric constraint is a limitation placed on an object, which can have two dimensions or more, because there are zero degrees of freedom. An object that is fully constrained cannot be geometrically altered; in other words, its angles and side lengths and positions cannot be changed unless the specification of one of the existing dimensions is altered first.
Full Answer >A symmetrical pattern is a pattern in which converging lines form an angle that somewhat resembles an acute angle. When two patterns are symmetrical, one becomes exactly like another when flipped or turned, according to Primary Resources.
