How Many Diagonals Does A Convex Quadrilateral Have?

WebThe formula that is used to find the number of diagonals in any polygon is, Number of diagonals = n (n-3)/2; where 'n' represents the number of sides of the polygon. In this case, there are 8 sides in an octagon. After substituting the value of 'n' = 8 in the formula, we get, Number of diagonals = n (n-3)/2 = 8 (8 - 3)/2 = (8 × 5)/2 = 20. 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°.
