Page 410 Spreadsheet Investigation: Angles of Polygons 1. For a regular polygon, the measure of each interior angle in the polygon can be found by dividing the sum of the measures of the interior angles by the number of sides of the polygon. So, the formula to find the measure of each interior angle in the polygon is “ 5 C2/A2”. 2. For a regular polygon, the sum of the measures of the exterior angles of the polygon can be found by multiplying the number of sides by the measure of the exterior angles. So, the formula to find the sum of the measures of the exterior angles of the polygon is “ 5 A2*E2”. 3. The formula for the sum of the measures of the interior angles is “ 5 (A2-2)*180”, which gives 2 180 for 1 side and 0 for 2 sides. 4. No, a polygon is a closed figure formed by coplanar segments. 5. A 15-sided polygon has 13 triangles. 6. The measure of the exterior angle of a 15-sided polygon is 24. 7. The measure of the interior angle of a 110-sided polygon is about 176.7.
