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. Area= 1/2bh perimeter= a + b+ c hypotenuse= c²= b²+a²






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






3. x+w> y+z






4. (amount of increase/original amount) x 100






5. Is the relation with ALL ordered pairs REVERSED.






6. Are the lines that bisect and are perpendicular to each of the three sides. The point where they meet is the center of the circumscribed circle.






7. V2/2- v2/2 - 1 (90-45-45)






8. x²






9. The distance from the center of the circle






10. Sin 60°






11. The product of an even number of negative numbers is






12. 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.






13. Any integer is divisible by 8 if






14. 5-12-13






15. 2k






16. Any integer is divisible by 5 if






17. A<x and x<b






18. All sides are equal and all of whose angles are equal. 1. can be inscribed in a circle and can be circumscribed about another circle. 2. each angle is equal to the sum of the angles divided by the number of sides 180(n-2)°/n.






19. In a triangle - if ?c(interior angle in triangle) and ?d(exterior angle out of triangle) are supplmentary angles - than ?a and ?b are remote interior angles to <d - thus - a +b+c = 180 (triangle) c+d = 180 (supplementary angles)






20. 1. determine a rough approximation of the square root of the number. 2. divide the number by all the primes that are less than the approx square root. If the number is not divisible by ANY of the these primes - then it is prime. If it IS divisible -






21. The lines that divide each angle of the triangle into two equal parts. these lines meet in a point that is the center of a circle inscribed in the triangle.






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






23. x +z > y+z






24. The sum of the interior angles is






25. xn<0 if n is odd and xn>0 if n is even






26. What % of m is n






27. C times as old as john


28. All three sides and all three angles are equal






29. Intersect at only one point - the point is the only solution to the pair of equations






30. 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*)






31. A pair of equations in two unknowns (each is graphed seperately and each is represented by a straight line)






32. Volume=lwh surface area= 2wh + 2hl + 2lw






33. The increase from x to y






34. In transversals






35. 180°






36. Area= bh perimeter= 2a +2b






37. Side a +side b of a ? is






38. 180°






39. If two lines are parallel - the slope of one is






40. y years ago






41. If y²= x - then y =






42. Less than 90°






43. Is - as - was - has - cost






44. Is the set of the second components of the ordered pairs






45. If b²-4ac < 0 - there are






46. V10






47. Volume= 4/3?r² surface area= 4?r²






48. The case where the two equations are equivalent (just two different forms of the same mathematical relation). Any point that satisfies either of the equations - automatically satisfies both






49. The quotient of any quantity (except 0) divided by zero is infinity






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