Was wondering if someone could solve this problem for me. All the vertices of a decagon (10 sided convex polygon) are to be connected by straight lines called the "diagonals". a) if a side of the decagon does not count as a diagonal, then how many diagonals can be drawn? b) if the decagon is drawn so that no more than two diagonals intersect at any one point, then into how many line segments will the diagonals be divided by the intersecting diagonals? Thanks!!!
