How many diagonals in a square
WebThere are 54 diagonals in a dodecagon. These diagonals can be calculated with the help of the formula: 1/2 × n × (n-3), where n = number of sides. In this case, n = 12. Substituting the values in the formula: 1/2 × n × (n-3) = 1/2 × 12 × (12 … WebThe kite is split into two isosceles triangles by the shorter diagonal. The 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].
