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 lines that divide each angle of the triangle into two equal parts. these lines meet in a point that is the center of a circle inscribed in the triangle.






2. Any arc length is less than






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






4. ?






5. N= number of objects (order matters!!!) k= rate at a time nPk= n!/(n-k)! (remember to cancel common numbers)






6. 1. square all choices given 2. select the closes choice that is too large and the one that is too small. 3. find the average of the two choices (not of the squares) 4. square the average - if it is greater than the original number - choose the lower






7. (sum of individual quantities or measures/ total number of quantities or measures)






8. Any number squared or raised to an even power is






9. 1/y-1/x x -y ? 0

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






14. Wx<wy






15. Square of hypotenuse = c² = a²+b² length of hypotenuse = c= va²+vb²






16. Sum of two even numbers is






17. A°






18. 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






19. When two parallel lines are crossed by a third straight line (transversal) - then






20. Area= 1/2bh perimeter= a + b+ c hypotenuse= c²= b²+a²






21. Sin 60°






22. x > y or y< x






23. Area= 1/2?r2 length= 1/2?d= ?r perimeter= d(1/2? +1)
