Find The Sum Of The Measures Of The Interior Angles Of The Following Convex Polygons. First determine the number of sides. She nailed four pieces of wood together at what she believes will be the four vertices of a square.
An interior angle is located within the boundary of a polygon. A polygon with 18 sides has an interior angle sum of 2880 digrees. Sum of angles of a 11-gon 11 - 2 x 9 x Sum of angles of a 11-gon To check.
15-gon Find the measure of each exterior angle of each regular polygon.
Polygon Interior Angles Theorem. For example a square would have 4 sides and a pentagon would have 5 sides. Next calculate the sum. How can she be sure that the canvas will be a square.
