11. the table below shows the relationship between the number of sides in a polygon, and the number
of non overlapping triangles that can be created by connecting a single vertex to all other
vertices in the polygon f(n).
n = number of sides in a polygon
f(n) = number of non overlapping triangles created
n
nth
f(n)
how many triangles will be created in a polygon with 'n' sides?
if 19 non overlapping triangles can be created, how many sides does the polygon have?
