  • 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 digit all the way on the right of a number

2. The mathematical chance of something happening. can be expressed as a fraction - ratio - decimal - or percent.

3. A unit of measure used to describe the size of an angle or part of a circle. a complete circle has 360 degrees

4. Comparison of two or more numbers - expressed in lowest terms

5. 'from now' ex. 7 years hence= 7 years from now

6. Having all sides equal. an equilateral triangle has three equal sides

7. A number whose only positive whole number facotrs are 1 and itself.

8. A whole number that can be either positive - negative - or zero.

9. The middle number in a group

10. To cut exactly in half. a line that does this to a 70 degree angle divides it into two 35 degree angles

11. Lines in the same plane that never meet

12. The product of two or more whole numbers. 40 is this of 5 because 58=40. therefore 40 is also this of 8

13. An angle that contains less than 90 degrees

14. A number or group of numbers represented by a letter or symbol. the value can vary depending on the mathematical relationship defined for it

15. A 5 sided polygon

16. One of two equal factors of a number

17. Two angles sharing one common side and a common vertex

18. A triangle having at least two equal sides and two equal angles

19. Two angles containing a total of 90 degrees

20. The number you get when you add a group of numbers and then divide by how many there are. also called an arithmetic mean

21. The 'steepness' of a line. determined with a fraction: rise/run

22. Number that are multiplied together. the ones for 6 are 1 - 2 - 3 - and 6.

23. Including the two extremes. the integers from 1 to 5 inclusive are 1 - 2 - 3 - 4 - and 5.

24. The amount of space contained in - or occupied by - a solid figure. expressed in in cubic units.

25. The line connecting the vertices of two opposite angles of a quadrilateral.

26. The line perpendicular to the base of a polygon - or the length of that line.

27. The number you get when you subtract one number from another.

28. The bottom of a fraction

29. A little number placed towards the upper right of a big number. the coefficient (big number) is multiplied by itself that many times.

30. A half-circle

31. A solid whose base and top are identical parallel circles. unless otherwise stated - sides are always perpendicular to bases

32. Two angles containing a total of 180 degrees

33. An arithmetic or algebraic expression that has some value on the left and some value on the right

34. The top number of a fraction

35. The number left over after you've divided one number into another number

36. The place where the x axis frosses the y axis. usually referred to as the point (0 -0)

37. In a right triangle - the longest side (the side opposite the right angle)

38. A line connecting one point on a circle with another

39. The number you get when you add two or more numbers

40. The symbol (v) that tells you to find the square root of a number

41. Two lines meeting to form right angles

42. The point equidistant from the ends of a line

43. An angle whose measure is more than 90 degrees and less than 180 degrees

44. A quadrilateral whose opposite sides are both parallel and equal in length and whose opposite angles are equal

45. A quadrilateral that has four 90 degree angles

46. The longest line you can draw from one point in a circle to another (the longest chord). The diameter is two times the length of the radius

47. The number you get when you multiply two numbers

48. The point where two lines meet to form part of a polygon

49. The distance from the center of a circle to any point on the circle

50. A Greek letter used to represent the relationship between the radius of a circle and its circumference and area.
