[b]Sum of Exterior Angles of Polygons[/b][br][br]For each polygon below, find the sum of the exterior angles.[br]Move the vertices, keeping each polygon convex, and find the new sum of the exterior angles for each polygon.[br]Did the values change?

Does the number of sides of a polygon effect the sum of the exterior angles of a polygon?[br]Does the size or shape of the polygon effect the sum of the exterior angles?[br][br]Check your hypothesis with two classmates. Is your hypothesis correct?[br][br]Consider this:[br]If the polygon was regular (look up what this means if you cannot remember), how would you determine the value of one exterior angle? Write a formula and check it with two classmates.[br]Test your hypothesis.
