Exploring Star Polygons

Draw 5 points (A through E) in a circular path clockwise Connect every second point to get Lines AC, CE, EB, BD, and DA measure the five angles A through E at the star points Draw the vertex of the star and observe what happens to the angle measures (They increase and decrease) Copy the table on the next page repeat steps 1-6 for a 6 and 7 pointed star

lets explore further

can you make the vertices convex or concave ? (yes you can) show how you did it in step 9 how did the sum of the angle measure change when a polygon became convex. ( when you move around the angles the measure change )
