WebApr 7, 2010 · It is an octagon with 8 sides. Let n be the number of sides = number of vertices. Then each vertex can be connected to n-3 other vertices, giving n(n -3) connections. However, this counts each vertex pair connection twice, so there are: n(n - 3) / 2 diagonals. Thus if there are 20 diagonals: n(n - 3) / 2 = 20 n2 - 3n = 40 n2 - 3n - 40 = 0 (n + 5)(n - 8) = 0 … WebThere are 6 diagonals extending from each of the 9 vertices of the nonagon above creating a total of 27 diagonals. Internal angles of a nonagon The sum of the interior angles of a nonagon equals 1260°. As shown in the figure above, six diagonals can be drawn to divide the nonagon into seven triangles.
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°.
