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.
For a heptagon, n=7. See Interior Angles of a Polygon. 51.429Â°. To find the exterior angle of a regular heptagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle. See Exterior Angles of a Polygon.
