Investigating the Sum of Polygon Interior Angles
1In each of the polygons, pick one vertex and draw all of the diagonals from that vertex. Notice how this divides each polygon into triangular regions 2.After you have drawn in all of the diagonals, complete the table on your worksheet. 3.Make a conjecture about the sum of the interior angles of any convex polygon. 4.Draw your own polygons of any size and test your conjecture!
