How many triangles can be formed by joining the vertices of an n-sided polygon?How many these triangles have
(i) Exactly one side common with that of the polygon?
(ii) Exactly two sides common with that of the polygon?
(iii) No side common with that of the polygon?
I am able to find out how many triangles can be made using the three vertices. but i am not able to unerstand the next three subquestions
(i) when one side iscommon then the no. of triangle will be n(n-3)
(ii) when two sides common with the polygon then it will be n
(iii) When no side is common with the polygon then it will be total - when one side is common - when two side is common
i.e C(n,3) - n(n-3)-n
