Page 410Spreadsheet Investigation: Angles ofPolygons1.For a regular polygon, the measure of eachinterior angle in the polygon can be found bydividing the sum of the measures of the interiorangles by the number of sides of the polygon.So, the formula to find the measure of eachinterior angle in the polygon is “5C2/A2”.2.For a regular polygon, the sum of the measures ofthe exterior angles of the polygon can be found bymultiplying the number of sides by the measureof the exterior angles. So, the formula to find thesum of the measures of the exterior angles of thepolygon is “5A2*E2”.3.The formula for the sum of the measures of theinterior angles is “5(A2-2)*180”, which gives2180 for 1 side and 0 for 2 sides.4.No, a polygon is a closed figure formed bycoplanar segments.5.A 15-sided polygon has 13 triangles.6.The measure of the exterior angle of a 15-sidedpolygon is 24.7.The measure of the interior angle of a 110-sidedpolygon is about 176.7.
