It has twelve faces, twenty vertices and thirty edges.
The exterior angle of a dodecagon (a polygon with 12 sides) can be calculated using the formula for the exterior angle of a regular polygon, which is ( \frac{360^\circ}{n} ), where ( n ) is the number of sides. For a dodecagon, ( n = 12 ), so the exterior angle is ( \frac{360^\circ}{12} = 30^\circ ). Therefore, each exterior angle of a regular dodecagon measures 30 degrees.
a crescent has 19 sides
Mo such shape/thing as a 'polgon'. If you mean ' polygon'. The word 'polygon' means a 2-dimensional shape (--gon) of many sides (poly--). So the word 'polygon' mean an many sided shape. For a specific number of sides it becomes;- trigon ( triangle) 3 sides quadragon ( quadrilateral ) 4 sides pentagon 5 sides et seq.,
10 sides.
There is no formula for how many sides there are in a polygon; the name of the polygon shows how many sides it has.
