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.
To find the sum of the interior angles of a heptagon, divide it up into triangles... There are five triangles... Because the sum of the angles of each triangle is 180 degrees... We get. So, the sum of the interior angles of a heptagon is 900 degrees.
