This lesson explains the diagonals of a polygon. Learn about a polygon's formula, how to find it, and see examples.
To find the measure of a missing interior angle of a polygon, you subtract the sum of the other angles from Sn. In this context, Sn is the sum of the interior angles of the polygon. What is the interior angle sum formula? Consider a polygon with n sides. The sum of the interior an...
Find your Math Personality!Polygon FormulaBefore starting with the polygon formula, let us recall the definition of a polygon. A polygon is a closed 2-D shape that has three or more straight lines. A polygon should have at least three sides. Each side of the line segment intersects with ...
If the shape is a polygon and it has eight sides, we call it an octagon. To find the area of an octagon we use the following formula. Area of octagon formula = 2 × s2× (1+√2). Where "s" denotes the length of the side of an octagon. What is the Area of an Octagon With...
Number of Diagonals = \[\frac{n(n-3)}{2}\] Simply subtract the total sides from the diagonals given by each vertex to another vertex to arrive at this formula. To put it another way, an n-sided polygon has n-vertices that can be connected in nC2 ways. ...
The augmenting array of dots of polygonal numbers has the following stages. The first polygonal number is always 1. The polygon’svertexcount is the second number. The third and subsequent values can be obtained by adding one point to each of two adjacent sides, followed by creating another ...
In order to find the measure of a single interior angle of a regular polygon (a polygon with sides of equal length and angles of equal measure) with n sides, we calculate the sum interior anglesor (n−2)⋅180(n−2)⋅180 and then divide that sum by the number of sides or nn...
= 0 subtract c/a from both sides of this equation. x 2 + (b/a)x = -c/a now, apply the method of completing the square. add a constant to both sides of the equation to make the lhs of the equation as complete square. adding (b/2a) 2 on both sides, x 2 + (b/a)x + ...

Perimeter of RectangleThe perimeter of a two-dimensional shape is the total length of the outline. To find the perimeter of a rectangle, we add the lengths of all four sides. Since opposite sides of a rectangle are always equal, we need to find the dimensions of length and width to find...
