  1. GT Geometry Unit 6: Quadrilaterals Jeopardy

  2. $100 What is the sum of the interior angles of a pentagon?

  3. $100 540 Degrees

  4. $200 What is the measure of each exterior angle of a regular octagon?

  5. $200 45 degrees

  6. $300 If each interior angle of a regular polygon is 140 degrees how many sides does the polygon have?

  7. $300 9 sides

  8. $400 If each exterior angle of a regular polygon is 72 degrees how many sides does the polygon have?

  9. $400 5 sides

  10. $500 If each interior angle of a regular polygon is 150 degrees what is the measure of each exterior angle?

  11. $500 30 degrees

  12. $100 Find x if the quad below is a parallelogram

  13. $100 X = 7

  14. $200 Find x if the quad below is a parallelogram

  15. $200 X = 12

  16. $300 Find x if the quad below is a parallelogram

  17. $300 X = 3

  18. $400 Find x if the quadrilateral below is a parallelogram

  19. $400 X= 33

  20. $500 Find x if the quadrilateral below is a parallelogram

  21. $500 X = 14.5

  22. $100 Can we prove this quadrilateral is a parallelogram?

  23. $100 Yes both pairs of opposite sides are congruent

  24. $200 Can we prove this quadrilateral is a parallelogram?

  25. $200 No, we don’t know that both pairs of opposite angles are congruent

  26. $300 Can we prove this quadrilateral is a parallelogram?

  27. $300 Yes, one pair of opposites sides is both congruent and parallel

  28. $400 Can we prove this quadrilateral is a parallelogram?

  29. $400 Yes, diagonals bisect each other

  30. $500 Can we prove this quadrilateral is a parallelogram?

  31. $500 Yes, the total sum of the angles of a quadrilateral is 360 degrees. Therefore x = 100. Since the opposite angles are congruent it is a parallelogram

  32. $100 If the quadrilateral below is a rhombus, find x

  33. $100 X = 4.5

  34. $200 If the trapezoid below is an isoceles trapezoid find x.

  35. $200 X = 12

  36. $300 If the trapezoid below is an isosceles trapezoid, find x

  37. $300 X = 14.5

  38. $400 If the quadrilateral below is a rhombus find x

  39. $400 X = 2 Diagonals of a rhombus bisect angles

  40. $500 If the quadrilateral below is a rhombus find x

  41. $500 X = 17 The diagonals of a rhombus are perpendicular so use the Pythagorean theorem

  42. $100 Find the area of the polygon

  43. $100 A = 70 Area of a rhombus = ½ (d1)(d2) D1 = 7 + 7 = 14 D2 = 5+5 = 10

  44. $200 Find the area of the quadrilateral

  45. $200 A = 64 Area of a trapezoid = ½ (b1+b2)h = ½ ( 6+10) 8

  46. $300 Find the area of the quadrilateral below. Hint (use the Pythagorean theorem to find the missing side.)

  47. $300 A = 192 The height of the rectangle = 12. 12 x 16 = 192

  48. $400 The quadrilateral has an area of 60 sq inches. Find x

  49. $400 x = 8
