it's a 12 sided shape and it has 54 diagonals :D
probably, 4. or maybe pi. i believe that the answer is 8.....:)))
A dodecagon has twelve vertices.
A dodecagon has 12 vertices.
A regular 12 sided dodecagon has 54 diagonals.
A dodecagon has 1/2*12*(12-3) = 54 diagonals.

There are 54 diagonals in a 12 sided shape
54
A undecagon has 44 diagonals. A dodecagon has 54 diagonals. An octagon has 20 diagonals. A heptagon has 14 diagonals.
it's a 12 sided shape and it has 54 diagonals :D
It is: 0.5*(144-36) = 54 diagonals
12-3 = 9
The formula is: 0.5*(n2-3n) = number of diagonals when n is the number of sides of the polygon
A polygon with n sides has 1/2*n*(n - 3) diagonals. So, for a polygon, with n = 12, there are 54 diagonals.
A doedecagon is 12 sided, I am not sure if it would be correct to say it consists of line segments, but if it is, then 12. There are also 35 distinct diagonals that can be drawn from the vertices and the dodecagon can be divided up into 8 triangles by drawing the diagonals.
