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.

23. All angles are right angles and diagonals are equal 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






24. Product of two odd numbers is






25. Is always a right angle.






26. The whole equals






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






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






29. The point where the line crosses the x-axis - y will always = 0 in this case






30. 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.






31. Area = ?r² circumference(perimeter)= 2?r






32. One angle is equal 90° and the other two angles are equal to the sum of 90°






33. Sin 60°






34. If an equation can be put into the form y= mx +b - then






35. x < y or y> x






36. If two lines are parallel - the slope of one is






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






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

43. Angle whose sides are two radii of the circle. The vertex of this angle is the center of the circle. The number of degrees is equal to the amount of arc length that the radd intercept.






44. 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)

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






49. Diagonal= sv2






50. 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.
