A regular or even an irregular dodecagon is a 12 sided polygon whose interior angles add up to 1800 degrees
A regular 12 sided dodecagon has 54 diagonals.
A regular or an irregular dodecagon both have 12 sides
54
Yes it can.
A regular dodecagon has six pairs of parallel lines.
it has twelve sides
It has 20 vertices or angles. * * * * * No! A dodecagon has 12 vertices. A polygon with 20 vertices is an icosagon.
Not sure about a duodecagon, but a regular dodecagon has 12 axes of symmetry.
The shape of the twelfth figure is a dodecagon. A dodecagon is a polygon with twelve sides and twelve angles. It is a regular dodecagon if all its sides and angles are equal. The interior angles of a regular dodecagon measure 150 degrees each.
Each interior angle of a regular 12 sided dodecagon measures 150 degrees
360/12 = 30 degrees
Assuming the shape is a regular dodecagon, the formula for calculating the perimeter for a dodecagon of side length n is equal to 12n.
