A flat 10-sided shape with sides of equal length is called a decagon. A solid 10-sided shape with faces of equal size and shape is called a decahedron.
Continue ReadingTwo-dimensional shapes are called polygons, which means they are flat, straight-sided and closed. Three-dimensional shapes are called polyhedrons. These are solid with flat faces. Polygons and polyhedrons with all sides or faces the same size are called regular and are named from the Greek words associated with the number of sides or faces they contain. Polygons and polyhedrons are two kinds of shapes studied in the branch of mathematics known as plane geometry.

Full Answer >A polygon with 10 sides is called a decagon. The word comes from the Greek words for "ten" ("deka") and for "angle" or "corner" ("gonia"). Decagons have 10 angles and 10 sides.
Full Answer >A 10-sided shape is known as a decagon. It is a two-dimensional polygon, which means it is a closed shape consisting of 10 straight lines. Sides may or may not be the same length.
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.
