Is a dodecagon a polygon with 12 sides?
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
What is the name of 12 sided polygon?
In geometry, a dodecagon or 12-gon is any twelve-sided polygon.
What property of a polygon does a dodecagon having 12 equal sides show?
Irregular dodecagons have unequal sides and angles. Also, a dodecagon can be a convex polygon or concave polygon. The sum of all the interior angles of the dodecagon is equal to 1800°….Facts on Dodecagon.

How many faces does a dodecahedron have?
12Dodecahedron / Number of faces
A regular dodecahedron or pentagonal dodecahedron is a dodecahedron that is regular, which is composed of 12 regular pentagonal faces, three meeting at each vertex. It is one of the five Platonic solids. It has 12 faces, 20 vertices, 30 edges, and 160 diagonals (60 face diagonals, 100 space diagonals).
Why is a 12 sided polygon called a dodecagon?
Sometime during the mid 1600s, a mathematician felt the need for a descriptive word for a 12-sided polygon. The word dodecagon comes from the Greek, dōdeka-, which means 12, and + -gōnon, which means angled. Dodecagons can be regular, meaning all interior angles and sides are equal in measure.
How many sides and vertices does a dodecagon have?
A dodecagon is a polygon with 12 sides and 12 vertices. “Do-” means “two” and “deca-” means “ten.”
What type of Polygon has 12 sides and 12 vertices?
Dodecagon is one of the types of polygons that has 12 sides, 12 vertices and 12 angles. Similar to other polygons, a dodecagon is also a two-dimensional plane figure. A regular dodecagon polygon has 12 equal sides and has 12 equal measures of angles. Irregular dodecagons have unequal sides and angles.
What are the properties of a dodecagon?
The properties of a dodecagon are listed below which explain about its angles, triangles and its diagonals. Each interior angle of a regular dodecagon is equal to 150°. This can be calculated by using the formula: 180n–360 n 180 n – 360 n, where n = the number of sides of the polygon. In a dodecagon, n = 12.
