WebThe interior angles of polygons follow certain patterns based on the number of sides, too. First of all, a polygon with n sides has n vertices, and therefore has n interior angles. The sum of these interior angles is equal to 180 (n-2) degrees. Knowing this, given all the interior angle measures but one, you can always figure out the measure of ...

WebMar 9, 2024 · A) To find the sum of the angles of a polygon, we use (n-2)(180), where n is the number of sides. We would then have (11-2)(180)=9(180)=1620. If the polygon is regular, we divide this by the number of sides; 1620/11 = 147.23. Thus all 11 angles would be obtuse in a regular 11-sided figure.
