What is the formula to find the number of diagonals in a polygon?
Suppose the polygon's vertices are denoted A 1 A 2 ...A n . We can fix one endpoint of the diagonal at A 1 and count the number of ways to choose from the remaining vertices. There are n-3 vertices to choose from, because we cannot count A ... Read More »

Suppose a polygon has n vertices (and sides). From each vertex, a diagonal can be drawn to all vertices, excluding itself and the two adjacent vertices. So n-3 diagonals can be drawn from each vertex. Multiplying by the full complement of n...

I don't think anyone knows who discovered it first. Since it's pretty obvious logically, it has probably been known for thousands of years. We can easily derive it using simple math: First, pick a vertex. A diagonal can be drawn to every ve...

For each vertex connecting it to any other vertex except the two adjacent vertices will create a diagonal. So if there are n vertices then from each vertex you can create n-3 diagonals. So n(n-3) will count all the diagonals twice (once fro...
