WebThe diagonal of a polygon formula is used to calculate the number of diagonals of a polygon. It says The number of diagonals of a polygon = n (n−3)/2 Here 'n' is the number of sides polygon has. Let us see the applications of the diagonal of a polygon formula in the following section. Solved Examples Using Diagonal of a Polygon Formula WebFigure %: A polygon is divided into triangles, and the sum of its interior angles is shown to be 180 (n-2) degrees. The above polygon has n = 6 sides. n-3 = 3 diagonals can be drawn from a given vertex, yielding n-2 = 4 triangles. (n-2)180 = 720 degrees of interior angles in a 6-sided polygon. This is only one way that triangles help ...

An n-sided polygon’s number of diagonal lines = n (n-3)/2, where n is the number of sides. Here we will also discuss the meaning of the diagonal line, diagonals for several polygons such as square, rectangle, rhombus, …
WebThe two lines are called diagonals of a square. Diagonal of a Square Definition. The diagonal of a square is a line that connects one corner to the opposite corner through the center. In other words, we can say that the diagonal is the slant line that connects the square’s opposite corners. A square has two diagonals that are equal in length. WebA diagonal of a polygon is a line from the vertex to a non-adjacent vertex. The number …
