  9. 100 points What is the name of a polygon with 6 sides?

  10. 100 Points A Hexagon!

  11. 200 Points What is the name of a polygon with 7 sides?

  12. 200 Points A Heptagon or Septagon!

  13. 300 Points What is the name of a regular polygon with an exterior angle of 36o?

  14. 300 Points N = 10 A Decagon

  15. 400 Points What is the name of a polygon with an interior angle sum of 12600?

  16. 400 Points • N = 9 • A Nonagon!

  17. 500 Points What is the name of a regular polygon with an interior angle of 150o?

  18. 500 Points N = 12 A dodecagon!

  19. 100 Points What is the formula or strategy you would use to calculate the measure of an exterior angle of a regular polygon?

  20. 100 Points Exterior Angle = 360/n

  21. 200 Points What is the formula you would use to calculate the sum of the interior angles?

  22. 200 Points Interior Sum = (n-2)180

  23. 300 Points What is the formula you would use to calculate one interior angle of a regular polygon?

  24. 300 Points Interior Angle = (n-2)180 n

  25. 400 Points If you are given the interior angle, how would you calculate the exterior angle?

  26. 400 Points The interior and exterior angles are supplementary, so Exterior = 180 - interior

  27. 500 points Set up the equation that you would use to solve for x. Don’t solve it. X + 100 X + 100 x0 x0 x0 x0 X + 100 X + 100

  28. 500 points 4x + 4(x+10) = 1080 Or 8x + 40 = 1080 X + 100 X + 100 x0 x0 x0 x0 X + 100 X + 100

  29. 100 Points Draw a polygon and label and interior angle.

  30. 100 points x

  31. 200 Points Draw a polygon and label the exterior angle.

  32. 200 Points x

  33. 300 Points What is the name of an 8 sided figure?

  34. 300 Points Octagon

  35. Daily Double!!

  36. 500 Points Draw a hexagon and label the central angle

  37. 500 Points

  38. 100 Points What is the sum of the interior angles of a 56-gon?

  39. 100 Points Sum = 9720o

  40. 200 Points What is the measure of one interior angle in a 14-gon?

  41. 200 Points Interior angle = 154.3o

  42. 300 Points If the measure of the exterior angle is 81o, what is the measure of the interior angle?

  43. 300 Points interior angle = 99o

  44. 400 Points Solve for x. 141o 140o 87o 85o X 135o

  45. 400 Points X = 1320

  46. 500 Points What are the measures of each angle? A 5x + 2 E B 2x + 10 2x + 10 3x + 4 3x + 4 D C
