What is a shape with 12 angles?
A dodecagon is a polygon with 12 sides, 12 angles, and 12 vertices. The word dodecagon comes from the Greek word “dōdeka” which means 12 and “gōnon” which means angle. This polygon can be regular, irregular, concave, or convex, depending on its properties.
What is 12 sided shape called?
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 a polygon with 12 sides and 12 vertices?
A dodecagon is a polygon with 12 sides and 12 vertices.
What 3d shape has 12 sides?
dodecahedron
In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” + ἕδρα hédra “base”, “seat” or “face”) or duodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid.

What is the total angle of a twelve sided polygon?
The total of the exterior angles of a twelve-sided polygon is 360°. The number of all possible diagonals in a twelve-sided polygon is given by the formula: The number of triangles formed by the diagonals from each vertex of a twelve-sided polygon is, n – 2 = 12 – 2 = 10.
How many sides and 12 vertices does a dodecagon have?
A dodecagon is a polygon with 12 sides, 12 angles and 12 vertices. The word dodecagon comes from the Greek word “dōdeka” which means 12 and “gōnon” which means angle.
What kind of shape is a 12 sided shape called?
What Is a 12-Sided Shape Called? A 12-sided shape is called a dodecagon. A dodecagon is a type of polygon, which is a two-dimensional shape comprised of straight lines. These lines connect to each other to form a closed shape.
When do we know two angles and one side?
“AAS” means “Angle, Angle, Side”. “AAS” is when we know two angles and one side (which is not between the angles).
