A dodecagon is a 12 sided shape made from 10 triangles
no triangles
get a cut out shape of octagon, then get cut out triangles and try to fit in the triangles covering all the octagon but here is the solution... j
Such as? If you can break the shape up into triangles you can find the area that way. Or, you can get into calculus-based equations if you have an equation for the random shape.
The easiest way to find out how many degrees in any shape is 180*(n-2) where n equals the number of angles in the shape. Thus, triangles have 180 degrees.
Originating from one vertex there are 27 triangles
To calculate this, you must find out how many triangles you can draw into the shape. Do this by taking the total number of sides (s) and taking away 2. This leaves you with how many triangles you can draw in the shape (t) from one vertex to another. (Not including outside lines!). Then, multiply the number of triangles in the shape by 180. This leaves you with how many degrees are inside that shape. (a)t = s-2a = t X 180This means there are 1800 degrees in a 12 sided polygon.
