Cloverdale River Park a great spot for wildlife viewing, and information about the park's riparian habitat is located along the trail. There are group picnic areas with barbecues and a large parking lot. Both include several wheelchair-accessible spaces. No lifeguard service is available.
Sum of interior angles of an n sided polygon = (2n - 4) * 90 degrees. Let us find the sum of the interior angles of a heptagon. Heptagon is a polygon with 7 sides. Sum of interior angles of a heptagon = (2 * 7 - 4) * 90 degrees. = 900 degrees. If heptagon is regular, then the value of an interior angle is $\frac{900}{7}$ degrees = 128.57 degrees.
1 The number of octagon diagonals is 20. 2  The sum of all interior angle = 1080 degrees. 3  Since the sides for an regular octagon are equal, the interior angle at each vertex is = $\frac{1080}{8}$ = 135 degrees. 4  The total exterior angle is 360 degrees.
