Formula to find number of diagonal in polygon
The formula to find the number of diagonals of a polygon is n (n-3)/2 where “n” equals the number of sides of the polygon. [8] Using the distributive property this can be rewritten as (n 2 - 3n)/2. You may see it either way, both equations are identical. This equation can be used to find the number of diagonals of any … See more WebThe kite is divided into two congruent triangles by the longer diagonal. The longer diagonal bisects the pair of opposite angles. The area of kite = 12× d1× d2, where d1, d2 are lengths of diagonals. Perimeter of a kite with sides a and b is given by 2 [a+b]. The sum of the interior angles of a kite = 360°.
