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. x/100






2. Is always a right angle.






3. In a triangle - the greatest angles lies






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






5. Any integer is divisible by 10 - if






6. 2k + 1






7. 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






8. A collection of anything - numbers - letters - objects - etc. written within brackets { } two are equal if they contain the same elements.(order does not matter)






9. The measure of an interior angle is






10. x + y






11. Sum of two odd numbers is






12. Wx>wy






13. Any integer is divisible by 6 if






14. 1. subtract each number from the average of the numbers 2. square the result of each of the numbers 3. add all those results and then divide by how many numbers you originally had. 4. take the square root of that result






15. 180°






16. ?






17. A subset of a set is






18. When two parallel lines are crossed by a third straight line (transversal) - then






19. ?






20. 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.






21. x older than y






22. 5-12-13






23. V2






24. x less than y






25. (x-y)(x-y) = (x-y)²






26. z>y






27. Wx<wy






28. 2k






29. Area= s² perimeter= 4s






30. 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.






31. 9-40-41






32. Square of hypotenuse = c² = a²+b² length of hypotenuse = c= va²+vb²






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






34. 1. solve the equation or inequality 2. use ONLY the solutions which satisfy the condition required - the set of all x such that x is greater than or equal to 10 R= {x: x=10}






35. 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 -






36. y years from now






37. Write down every member in one or both of the sets - the union of two sets is a new set. the union of set A and B is written as A?B






38. ? if a side < b side - then






39. x(y+z)






40. The distance between two parallel lines or from a point to a line always means






41. C²= a²+b² and angle x and y are equal to 90°
