Lauren Sims MTH 210 March 7, 2011 1. 28. This is deductive reasoning; this is due to not actually knowing if it will rain on Thursday. Weather is very unpredictable. 30. This is inductive reasoning. If the person receives the check form their father they would buy the Buick and since the father gave the person the check they was able to purchase the vehicle 1.2 Points, Lines, and Planes 20. True 22. True 26 Yes because for every line it exist at least 2 distinct points. 28. Yes because the lines are considered to be parallel. 1.3 Segments, Rays, and Angles 38. The supplement of the complement of an angle measuring 50 degrees would be 130 degrees. 42. The answer would be 67.5 degrees X = 3 (90 – X) X = 270 – 3X X + 3X = 270│4X = 270

X = 270/4 = 67.5 60. The answer would be two.
