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.
The sum of the measures of the interior angles of a convex polygon with n sides is $ (n-2)180^{\circ} $ Examples: Triangle or ( '3-gon') sum of interior angles: $$ (\red 3-2) 180 = 180^{\circ} $$ Quadrilateral which has four sides ( ' 4-gon') sum of interior angles: $$ (\red 4-2) 180 = 360^{\circ} $$ Hexagon which has six sides ( '6-gon')
