WebSep 7, 2024 · The diagonals are: AC AD BD BE CE Here we have two diagonals containing A, two containing B, two containing C, two containing D, and two containing E. This way of describing it suggests the beginning of a pattern! So for 4 sides there is one diagonal for each vertex and for 5 there are two. Why?
WebTo make a diagonal, we have to choose another vertex out of of the possible n − 3 vertices (All vertices excluding the first vertex and its 2 neighbor). However n ( n − 3) double counts the number of diagonals so the answer should be n ( n − 3) 2.
