    Answer:

    54 diagonals

    Step-by-step explanation:

    The equation for finding number of diagonals in a n-sided polygon is, n(n-3)/2

    For 12 sided polygon, number of diagonals is= 12(12-3)/2 =54.

    One more simple example, we can check with our most familiar polygon

    In a square ( n=4), number of diagonals = 4(4-3)/2 = 2.
