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. y years ago






2. Sum of two even numbers is






3. A+b=c+ d=d






4. 1/y-1/x x -y ? 0






5. Any integer is divisible by 5 if






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






7. ?






8. If two lines are perpendicular - the slope of one is the






9. M=number of favorable ways n= total number of ways (two events occurring is the prob of the first times the prob of the second)






10. 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*)






11. 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






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






13. 1/x + 1/y x -y ? 0






14. Have two equal sides and two equal angles formed by the equal sides and the unequal side.






15. 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.






16. Area= 1/2h(b1+b2) perimeter= b1+b2+c+d






17. Sin 60°






18. 180°






19. 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.






20. ? if a side < b side - then






21. What % of m is n






22. x - (n/100)x






23. V3






24. 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. Angle whose sides are two radii of the circle. The vertex of this angle is the center of the circle. The number of degrees is equal to the amount of arc length that the radd intercept.

33. All odd numbers end in the digits of






34. Every set is a subset of
