  1. White Board Review for Honors Geometry Midterm Exam

  2. Midterm Info. For 1st Period • Wednesday, January 16 • 8:00 – 9:15 You need to bring: • Pencils, erasers, calculator • Your textbook to turn in!! 

  3. Midterm Info. For 2nd Period • Thursday, January 17 • 8:00 – 9:15 You need to bring: • Pencils, erasers, calculator • Your textbook to turn in!! 

  4. 8. Solve the following equations for x. a. [ a: x = 2.5, b: x = –1.5, 1 ] b.

  5. 13. The solution(s) to is/are: A. 5 only B. 5 and –5 C. 2, 5, and –5 D. 2 and 25 E. none of these [ B ]

  6. 16.Find the equation of the line through the points (–6, 3) and (9, 8).

  7. Use the following for the next three problems: Given . 21. The y – intercept is A. (0, 6) B. (0, –6) C. (0, –4) D. (0, 4) E. None of these A

  8. 22. The x – intercept is A. (6, 0) B. (-6, 0) C. (-4, 0) D. (4, 0) E. None of these C (Wrong on sheet)

  9. What is the slope of a line parallel • to the following line? 3/2

  10. 24. A line goes through the points (5, –1) and (7, –5). A line perpendicular to that line is A. B. C. D D. E. None of these

  11. 19. If you graphed the line would the point (60, 41) be on the line? Justify your answer completely. [ Yes, since (2/3)•(60) + 1 = 40 + 1 = 41, the point satisfies the equation, so the point is on the line. ]

  12. 25. Given the system C , what is the value of a - b? A. 11 B. 3 C. 1 D. –1 E. None of these

  13. 26. A line goes through the points (–10, –23) and (20, 37). Another point on the line is A. (2, 19) B. (2, –3) C. (2, –53) D. (2, 1) E. None of These D

  14. To decide if his class will have a quiz today, he will flip a coin three times. If all three results are heads or all three results are tails, he will give the quiz. Otherwise his students will not be tested. What is the probability that his class will take the quiz? Answer: 1/4

  15. What is the area of the square below? 40.5 sq. in 9 in.

  16. Given ∆ABC~∆WYZ, what is the value of x? X=10.4

  17. What is the smallest possible whole number value for n that will still form a triangle? n = 7

  18. Given isosceles triangle ABC with AB = BC. If angle A = 2x +10 and angle B = 6x – 20, what is the measure of <C? Angle C = 46 degrees

  19. 7. Willis has just finished sorting all of his triangles in his collection into several boxes. The blue box contains only equilateral triangles. The green box contains only scalene triangles. The red box contains only isosceles right triangles, while the yellow box contains isosceles triangles that are not right. If Willis is to choose two triangles at random from each box, what is the probability the two chosen triangles are similar? Note: you need to answer for each box, and you may have to give a reasonable estimate for some. AHH! WORDS!! [ The probability of choosing similar triangles from the blue box (equilateral) is 1 since all equilateral triangles are similar. We cannot determine the probability of choosing similar triangles from the green box; some scalene are similar, but it isn’t guaranteed. The probability of choosing similar triangles from the red box is also 1 since all isosceles right triangles are similar. And from the yellow box: we cannot determine since some may or may not be similar. ]

  20. 29. Solve the equation for x: x = 3

  21. THE END Good luck on your midterm!
