Directions:
1. Move around the points of the triangle, or the 3-sided polygon. What is the sum of the interior angles of a triangle no matter how you move it around?2. Do the same with the 4-sided polygon. What is the sum of the interior angles of this polygon?
3. Do the same with the 5-sided polygon. What is the sum of the interior angles of this polygon?
4. Do the same with the 6-sided polygon. What is the sum of the interior angles of this polygon?
6. Do you see any pattern? What is it? Can you relate this pattern to the number of degrees in a triangle?
