What is a decagon in math?
A decagon is a ten-sided polygon. In particular, a decagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular decagon.
What is a decagon called?

What is ten-sided shape called?
decagon
Your geometry teacher would also tell you that a decagon is a polygon. The word decagon comes from Greek roots, deka, or “ten,” and gōnia, “angle or corner.” Any ten-sided shape can be called a decagon, whether it’s a street sign or the doodle you draw in your notebook during math class.

How to calculate the area of a decagon?
Area [ change | change source] The amount of space a regular decagon takes up is a is the length of one of its sides. An alternative formula is where d is the distance between parallel sides, or the height when the decagon stands on one side as base. By simple trigonometry .
What are the gyration orders of the decagon?
Blue mirrors are drawn through vertices, and purple mirrors are drawn through edges. Gyration orders are given in the center. The regular decagon has Dih 10 symmetry, order 20. There are 3 subgroup dihedral symmetries: Dih 5, Dih 2, and Dih 1, and 4 cyclic group symmetries: Z 10, Z 5, Z 2, and Z 1.
What does a regular skew decagon look like?
A regular skew decagon is seen as zig-zagging edges of a pentagonal antiprism, a pentagrammic antiprism, and a pentagrammic crossed-antiprism . A skew decagon is a skew polygon with 10 vertices and edges but not existing on the same plane.
