What is the interior angle of a 12 sided polygon?
150°
A regular dodecagon is represented by the Schläfli symbol {12} and can be constructed as a truncated hexagon, t{6}, or a twice-truncated triangle, tt{3}. The internal angle at each vertex of a regular dodecagon is 150°.
What are the interior and exterior angles of a 12 sided polygon?
Properties of a dodecagon Here are the properties of a 12-sided shape: Each interior angle of a regular dodecagon is equal to 150°. Each exterior angle of a regular dodecagon is equal to 30°.
What is the exterior angle of a regular polygon having 12 sides?
Thus, each exterior angle of a regular polygon of 12 sides = 360o/ 12 = 30.
What is a 12-sided 3d shape called?
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 interior angle of a 24 sided polygon?
165°
In geometry, an icositetragon (or icosikaitetragon) or 24-gon is a twenty-four-sided polygon….Icositetragon.

What is each interior angle of a regular polygon with 14 sides?
about 154.3
The measure of each interior angle of a regular polygon with 14 sides is about 154.3.
Can a regular polygon have an exterior angle of 25?
Answer: It is not possible to have a regular polygon each of whose exterior angle is 25. Reason :- The formula is (360/n).. and 360 is not exactly divisible by 25.
Is it possible to have a regular polygon with each exterior angle 75 degree?
No it is not possible…
How many sides has a dodecahedron?
twelve faces
From left to right the solids are tetrahedron (four sides), cube (six sides), octahedron (eight faces), dodecahedron (twelve faces), and icosahedron (twenty faces).
What are the interior and exterior angles of a polygon?
Exterior Angles of a Polygon. At each vertex of a polygon, an exterior angle may be formed by extending one side of the polygon so that the interior and exterior angles at that vertex are supplementary (add up to 180). In the picture below, angles a, b c and d are exterior and the sum of their degree measures is 360.
What is the sum of the interior angles of a polygon?
The sum of the measures of the interior angles of a polygon is always 180(n-2) degrees, where n represents the number of sides of the polygon. The sum of the measures of the exterior angles of a polygon is always 360 degrees.
What is the formula for interior angles?
An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.
What is a 12 sided polygon called?
Dodecagon: It is a twelve-sided polygon and is also called as 12-gon. All the sides and interior angles are of equal length with the measurement equal to 150 degrees and the measurement of the center angle is equal to 360 degrees.
