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.

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






8. x+w> y+z






9. If y²= x - then y =






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






11. 1. determine a rough approximation of the square root of the number. 2. divide the number by all the primes that are less than the approx square root. If the number is not divisible by ANY of the these primes - then it is prime. If it IS divisible -






12. Area= 1/4s² v3 perimeter= 3s altitude= 1/2s v3






13. 8-15-17






14. Are the lines drawn from each vertex to the midpoint of its opposite side. they cross at a point that divides each individual ______into two parts.






15. M= y2-y1/x2-x1






16. ?






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






18. Is always a right angle.






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






20. Diagonal= sv2






21. Between 90° and 180°






22. 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.






23. Sin 45°






24. N= combinations taken (order does not matter) r= rate at a time nCr or C(n -r) = (n)!/(r)! (remember to cancel out common numbers)






25. ?






26. The length of a segment whose endpoints are (x1 -y1) and (x2 -y2)






27. In a triangle - if ?c(interior angle in triangle) and ?d(exterior angle out of triangle) are supplmentary angles - than ?a and ?b are remote interior angles to <d - thus - a +b+c = 180 (triangle) c+d = 180 (supplementary angles)






28. 1. solve the equation or inequality 2. use ONLY the solutions which satisfy the condition required - the set of all x such that x is greater than or equal to 10 R= {x: x=10}

36. N is what % of m






37. V2






38. 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






39. 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.
