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.

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






3. ?






4. 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)






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






6. The decrease from x to y

16. 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






17. Angles directly across each other are equal






18. Is the relation with ALL ordered pairs REVERSED.

24. 8-15-17






25. Every set is a subset of






26. A subset of a set is






27. A chord through the center of the circle






28. If under the operation - any two members of the set constitute an element of the set ( * the product of the elements multiplied by themselves must also be an element of the set*)






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






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






31. Volume= e(edge)³ surface area= 6e²






32. All odd numbers end in the digits of
