GRE Math Strategies

Subjects : gre, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. In transversals






2. A line that is perpendicular to a radius and that passes through only one point of the circle.






3. ?






4. The length of a segment whose endpoints are (x1 -y1) and (x2 -y2)






5. Angle whose sides are two chords. The vertex of the angles lies on the circumference of the circle. The number of degrees of the angle is equal to 1/2 the intercepted arc






6. x less than y






7. Is a subset of every set






8. The percent decrease from x to y ( y<x)






9. Is drawn from the vertices perpendicular to the opposite sides. The lengths of these lines are useful in calculating the area of the trinagle since the area of the triangle is 1/2bh and the height and the _____are the same.






10. The product of an odd number of negative numbers is






11. x +z > y+z






12. Sum of an odd and an even number is






13. Product of an even number and any other number is






14. Any arc length is less than






15. All three sides and all three angles are equal






16. x= -b + vb²-4ac/2a and x = -b - vb²-4ac/2a






17. The sum of any two sides of a triangle is greater than






18. Then their intersection is the null or empty set - written as Ø






19. x>z






20. (3+5) +6= 3+ (5+6) and (3x5)6= 3(5x6)






21. Volume= bh or ?r²h surface area= 2?rh (w/o bases) or 2?r(h+r) with bases






22. Write down every member that the two sets have in common. The intersection of the sets A and B is a set written AnB






23. 90°






24. If under the operation - any two members of the set constitute an element of the set ( * the product of the elements multiplied by themselves must also be an element of the set*)






25. Set of solutions to an equation






26. Distributive axiom - commutative axiom of addition and multiplication - associative axioms of addition and multiplication






27. One angle is equal 90° and the other two angles are equal to the sum of 90°

29. V10






30. 180°






31. M= y2-y1/x2-x1

41. Less than 90°






42. 1/2d






43. x older than y






44. ?






45. The point where the line crosses the y-axis - x will always = 0 in this case
