Find the number of sides the polygon has. Find the sum of measures of interior angles of a convex decagon. For the hexagon find the sum of the interior angles of the polygon. Find the interior and exterior angles of a 9-sided polygon. What is the sum of the measures of the exterior ...
Polygons; Properties and Interior Angles:In geometry, polygons are defined as those planer figures that are enclosed by line segments, and at least three line segments are required to form a polygon. The polygons of three sides are known as the triangles while the polygons of...
To find the sum of the interior angles of a polygon, we use the angle sum theorem. This states that the sum of the interior angles will equal the number of sides minus two times 180 degrees. The formula is (# of sides - 2) X 180 degrees = sum of in...
