1. In each of your groups of four pair up with only one computer for every two people.
2. Construct a triangle with the polygon tool.
3. Construct a ray on each side of the triangle.
4. Now measure the interior angles of the triangle and the exterior angles. Find the sum of each of these and record in your table. Move the vertices of the triangle do the sums of interiors or exterior angles change?
5. Now construct a quadrilateral and repeat steps four and five from above for each angle. Make sure to record your findings in the table provided.
6. Do the same for a pentagon, hexagon, etc. until you find a pattern.
