How to Find How Many Diagonals Are in a Polygon: 11 Steps
Web(diagonals to itself and one either side are not counted). Formula for the number of diagonals. As described above, the number of diagonals from a single vertex is three less than the the number of vertices or sides, or (n-3). There are N vertices, which gives us n(n-3) diagonals But each diagonal has two ends, so this would count each one twice. Pascal's theorem (also known as the "Hexagrammum Mysticum Theorem") states that if an arbitrary hexagon is inscribed in any conic section, and pairs of opposite sides are extended until they meet, the three intersection points will lie on a straight line, the "Pascal line" of that configuration.
