A shape that has 10 sides is call a decagon. A decagon is a type of polygon, which is a two dimensional shape with straight lines. These lines connect to each other to form a closed shape.
Know MoreThere are several types of decagons. An equilateral decagon is a decagon with equal length sides while an equiangular decagon has equal angles. A regular decagon has equal angles of 144 degrees each and sides of the same length. If the sides or angles are not equal, then the decagon is irregular. If none of the internal angles are greater than 180 degrees, then it is a convex decagon. If at least one angle is greater than 180 degrees, then the decagon is convex.

Full Answer >A shape that has three unequal sides is a scalene triangle. A shape that has four unequal sides is a quadrilateral. A shape that has more than four unequal sides is an irregular polygon.
Full Answer >A shape with 24 sides is called an icosikaitetragon. Greek prefixes are used for naming shapes by the number of sides. Numbers above 20 have additional special rules that must be followed to construct their names.
Full Answer >A regular shape, also known as a regular polygon, is a shape that has sides that are all equal. If there are sides of differing lengths, these shapes are known as irregular polygons.
