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 sum of any two sides of a triangle is greater than






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






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






4. x/100






5. A/A¹ = B/B¹= C/C¹

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






8. Any integer is divisible by 6 if






9. The sum of the interior angles is






10. Product of an even number and any other number is






11. 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.
