Polygons - Math is Fun

WebPolygon. A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges. The point where two line segments meet is called vertex or corners, henceforth an angle is formed. WebWe know that each exterior angle is supplementary to the interior angle. Thus, from the above formula, we can derive each exterior angle = [180°n -180°n + 360°]/n = 360°/n. Therefore, the sum of exterior angles of a … WebWe can find the number of diagonals of the given polygon with the formula, Number of diagonals = n(n-3)/2. Substituting the value of n = 15. n(n-3)/2 = 15(15-3)/2 = (15 × 12)/2 = 90. Therefore, the polygon has 90 diagonals. Example 2: If the length and width of a rectangle is 12 units and 5 units respectively. Find the length of its diagonal. bluetooth hco5 and hc06
