Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2.

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°.
WebFeb 17, 2024 · A nonagon has 9 − 3 = 6 diagonals connecting to each vertex. The number 3 is not arbitrary here – from any vertex, diagonals cannot connect to the vertex itself or to the vertices that they are “1 away” from, because it would be edges. That makes 3 vertices from every vertex that aren’t included. WebPolygon Calculator. Use this calculator to calculate properties of a regular polygon.
