Question

Number of points of intersection of convex hexagon

Answer 1

Step-by-step explanation:

Diagonals made by using all the choosen vertices only make 1 intersection.Therefore points of intersection of the diagonal made inside the polygon = nC4 = n! / ( n - 4 )! * 4! maximum number of points of intersection of the diagonal inside the nonagon ( n => 9 ) = 9C4 = 9! / 4!
