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

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

3. A half-circle

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

5. The bottom of a fraction

6. The number you get when you divide one number into another number

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

8. One of two equal factors of a number

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

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

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

12. An angle that contains less than 90 degrees

13. Two lines meeting to form right angles

14. The number you get when you multiply two numbers

15. A rectangular solid with six square sides or faces. also - a number raised to the third power

16. The point equidistant from the ends of a line

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

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

19. The digit all the way on the right of a number

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

21. The middle number in a group

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

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

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

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

26. Lines in the same plane that never meet

27. Triangles that have the same angles and are the same size. the three angles and three sides of one triangle is equal to the three angles and three sides of the other

28. Formed by two lines that either intersect (cross each other) or start from the same point. the opening is measured in degrees and can be thought of as a fraction of a circle's 360 degrees

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

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

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

32. Two triangles with exactly the same three angles. Similar triangles do not have to be the same size.

33. The top number of a fraction

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

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

36. A triangle that contains a 90 degree angle

37. 'in the same order'

38. With two fractions expressed as an inequality - to multiply the numerator of one fraction times the denominator of the other

39. 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

40. A whole numeral. there are 10 of them: 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - and 9.

41. Formula used to describe the relationship among the lengths of the sides of a right triangle

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

43. A section of a circle - also known as a little curved thing

44. A quadrilateral that has four 90 degree angles

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

46. A quadrilateral that has four 90 degree angles and four equal sides. also - a number raised to the second power.

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

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

49. The amount of space inside a two-dimensional (flat) object. measured in square units

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