11. Use the Spider Tool to confirm that the first two rotations in the table make an equilateral triangle and a square. Then complete the table by finding rotations that give regular polygons with 5 and 6 sides. (These are called regular pentagons and regular hexagons.) Make a conjecture about how you can find the rotation needed to make a regular polygon with n sides. (4 points: 1 point for each rotation, 2 points for a valid conjecture) Figure Number of sides Rotation Equilateral triangle 120 Square 4 90 Regular pentagon 5 Regular hexagon 6.
