16. Polygons for $200 Give the best name for the figure with the following properties: Opposite sides are parallel and congruent

17. Answer Parallelogram Back

18. Polygons for $300 Give the best name for the figure with the following properties: The diagonals bisect each other and are perpendicular

19. Answer Rhombus Back

20. Polygons for $400 What is the formula for the number of degrees in any polygon and where does it come from?

21. Answer Back Degrees = (n-2)*180, where n is the number of sides in the figure It comes from drawing all the diagonals from one vertex (breaking the shape into triangles)

22. Polygons for $500 Quadrilaterals are broken into three groups for naming based on one property. What is that property?

23. Answer Back The number of parallel sides

24. Congruence for $100 What are the three ways to determine if two triangles are congruent using only three pieces of information?

25. Answer SSS, ASA, SAS Back

26. Congruence for $200 What does CPCTC stand for?

27. Answer Back Corresponding parts of congruent triangles are congruent. In other words, if two triangles are congruent then the angles and sides that are in the same position on each triangle are also congruent.

28. Congruence for $300 Are the two triangles congruent? If so, how do you know?

29. Answer Yes, they are by SAS. Two sides are given as congruent and the included angles are congruent because they are vertical angles Back

30. Congruence for $400 Are the two triangles congruent? If so, how do you know?

31. Answer Not necessarily. Although they could be congruent, there is not enough information to tell for sure. SSA is inconclusive. Back

32. Congruence for $500 Are the two triangles congruent? If so, how do you know? Given: AB bisects angle A A B C D

33. Answer Yes, they are congruent by SAS. One pair of sides are congruent (given). Side AB is congruent to itself, and the angles CAB and DAB are congruent (definition of angle bisector. Back

34. Circles for $100 Where does pi come from?

35. Answer The circumference of a circle divided by the diameter of a circle. Back

36. Circles for $200 Define: Circle

37. Answer Back The locus of all points equidistant from a given point (the center)

38. Circles for $300 What is a central angle?

39. Answer Any angle whose vertex lies on the center of the circle Back

40. Circles for $400 The circumference of a circle is 10cm. To the nearest tenth, what is the radius of the circle?

41. Answer C = 2(pi)*r 10 = 6.28r r = 1.6cm Back

42. Circles for $500 Given that a sector is 55% of a circle, how many degrees are in the central angle of the sector?

43. Answer 0.55 = 360x x = 198 degrees Back
