A dodecagon can be drawn by drawing a polygon with 12 sides and 12 angles. All sides and angles have to be equal. * * * * * The first sentence is correct, the second is utter nonsense. There is no reason for a dodecagon - or a polygon with any number of sides - to have equal sides or equal angles.
A 12 sided shape with equal sides and with equal interior and exterior angles
It is regular if all its sides are equal AND all its angles are equal. Otherwise, it is not regular.
It is a dodecagon. While it is irregular, so is a dodecagon with equal sides but unequal angles, so "irregular" is not enough.
If the shape is flat is is called a: dodecagon If it is a 3 dimensional object it is called a dodecahedron
A dodecagon has 12 vertices.
It has 20 vertices or angles. * * * * * No! A dodecagon has 12 vertices. A polygon with 20 vertices is an icosagon.
A dodecagon has 12 interior angles that add up to 1800 degrees.
Sum of exterior angles of an n-gon is 360 degrees. A dodecagon has 12 exterior angles which are all equal and so each is 360/12 = 30 degrees.
A dodecagon has 12 vertices (corners).
The 12 interior angles of a dodecagon add up to 1800 degrees
A decagon is a 2-dimensional shape bounded by 12 straight sides. In a regular dodecagon all the sides are equal and all the angles are equal.
