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. R²






2. 360°






3. 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.






4. M?A = m?D m?B= m?E m?C=m?F and a/d=b/e=c/f






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






6. x < y or y> x






7. Area= l x w perimeter = (2l)(2w)






8. Is - as - was - has - cost






9. Sin 45°






10. Is a rectangular rhombus 1. all four sides are equal 2. opposite pairs of sides are parallel 3. diagonals are equal - are perpendicular to each other - and bisect each other. 4. all the angles are right triangles 5. diagonals intersect the vertices a






11. (amount of decrease/original amount) x 100






12. Any line that connects two points on a circle.






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






14. M= y2-y1/x2-x1






15. Any integer is divisible by 10 - if

17. Sum of two even numbers is






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






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