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. The angles opposite to sides that are equal in length have






2. 2k + 1






3. xw> yz






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






5. x more than y






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






7. ?






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






9. Less than 90°






10. 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






11. x/100






12. x older than y






13. x(y-z)






14. Sum of an odd and an even number is






15. A closed plane whose sides are straight lines. The sum of the angles is equal to 180(n-2) - where n is the number of sides.






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






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






18. 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.






19. The percent increase from x to y (y>x)






20. x>0 and y>0 or x<0 and y<0






21. B>c+ d>e






22. x younger than y

31. Two tangents to a circle from the same point outside of the circle are always






32. x + (n/100)x






33. 1.each pair of opposite sides are equal 2. the diagonals bisect eachother 3. the opposite angles are equal 4. one diagonal divides it into two congruent triangles and two diagonals divides it into two pairs of congruent triangles






34. 1. round the numbers being multiplied to one more place than it is being asked. 2. Multiply the rounded off numbers 3. round of product to desired number of places






35. 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
