Star Polygons
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 )
