In geometry, a decagon is known as a ten-sided polygon or ten-gon. A decagon is a ten-sided polygon with ten vertices and ten angles. Thus, a decagon shape can be defined as a polygon having ten sides, ten interior angles, and ten vertices. Based on the sides of a decagon, they are broadly classified into regular decagons and irregular decagons. A regular decagon has 35 diagonals and 8 triangles.

Exterior angle of a decagon

A decagon is a sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. Polygons get their name from Greek, meaning "many-angled," because all polygons have multiple interior angles. They close in a two-dimensional space using only straight sides. Drawing a decagon takes no skill; simply draw 10 line segments that connect, and you have it. Drawing a concave decagon is actually fairly easy: make a five-pointed star and fill it in. That is the star that appears 50 times on the Unites States flag, and the outline of such a pentagram five-pointed star is a decagon. A regular decagon has 10 equal-length sides and equal-measure interior angles. All polygons can be drawn as regular equal-length sides, equal-measure interior angles or irregular not restricted to congruent angles or sides. Because it is a challenging shape to make, the regular, convex decagon is popular with coins like those from Australia, Belize and Hong Kong. Irregular decagons must simply have 10 sides closing in a space, but the lengths of their sides can vary greatly. Most polygons can be convex or concave. So far all the decagons discussed - regular, irregular, concave, and convex - share the same properties:. Decagons can be simple or complex. A simple decagon has no sides crossing themselves.

Irregular decagons must simply have 10 sides closing in a space, but the lengths of their sides can vary greatly.
