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+y) (x-y)






2. x < y or y> x






3. Less than 90°






4. A chord through the center of the circle






5. 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.






6. Pairs of opposite angles formed by the intersection of two straight lines. always equal to each other






7. Parallel and never intersect - they have no solution at all - they are parallel with the same slope






8. Set of solutions to an equation






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






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






11. /100 (the ______ number over 100)






12. A¹






13. x+w> y+z






14. 1. square all choices given 2. select the closes choice that is too large and the one that is too small. 3. find the average of the two choices (not of the squares) 4. square the average - if it is greater than the original number - choose the lower






15. In a triangle - the greatest angles lies
