The internal angle at each vertex of a regular dodecagon is 150°. ... A skew dodecagon is a skew polygon with 12 vertices and edges but not existing on the same ...
If every internal angle of a simple polygon is less than a straight angle (π radians or 180°), then the polygon is called convex. In contrast, an external angle (also called a turning angle or exterior angle) is an angle formed by one side of a simple polygon and a line extended from an adjacent side. [1]: pp. 261–264
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon. [1] The total sum of the interior angles of a simple decagon is 1440°. Regular decagon

As n approaches infinity, the internal angle approaches 180 degrees. For a regular polygon with 10,000 sides (a myriagon) the internal angle is 179.964°. As the number of sides increases, the internal angle can come very close to 180°, and the shape of the polygon approaches that of a circle. However the polygon can never become a circle.
The measure of the central angle and exterior angle of a dodecagon, which is the petrie polygon of the 24-cell. The number of sides of a triacontagon, which in turn is the petrie polygon of the 120-cell and 600-cell. The number of edges of a dodecahedron and icosahedron, of vertices of an icosidodecahedron, and of faces of a rhombic ...
This dihedral angle, also called the face angle, is measured as the internal angle with respect to the polyhedron. An angle of 0° means the face normal vectors are antiparallel and the faces overlap each other, which implies that it is part of a degenerate polyhedron. An angle of 180° means the faces are parallel, as in a tiling. An angle ...
One interior angle in a regular icositetragon is 165°, meaning that one exterior angle would be 15°. ... Isogonal truncations of regular dodecagon and dodecagram
