WebThe formula for the number of diagonals in a polygon with n sides is: n (n-3)/2. where n is the number of sides of the polygon. In the case of a triangle, we have n = 3, so we can substitute this value into the formula and get: 3 (3-3)/2 = 0. WebMar 25, 2024 · 6 × ( 9) Removing the brackets, we will get, 6 × 9 = 54. Hence, there are 54 diagonals in a polygon having 12 sides. Note: We can calculate each interior angle by using the formula: 180 n − 360 n. where n is the number of sides of the polygon. And the sum of the interior angles can be calculated using the formula: ( n − 2) × 180 ∘.
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°.
