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

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

3. A three sided polygon. the angles of a triangle total 180 degrees

4. One after the other - without skipping. numbers in order.

5. An angle that contains less than 90 degrees

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

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

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

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

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

11. 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

12. Lines in the same plane that never meet

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

14. 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

15. The number you get when you multiply two numbers

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

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

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

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

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

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

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

23. The point equidistant from the ends of a line

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

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

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

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

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

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

30. A triangle that contains a 90 degree angle

31. The sum of the lengths of all the sides of a polygon

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

33. A quadrilateral that has four 90 degree angles

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

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

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

37. An integer

38. A 6-sided polygon

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

40. The bottom of a fraction

41. Two angles containing a total of 90 degrees

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

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

44. 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

45. The 'length' of a circle - measured from one point then all the way back to that point

46. Two angles containing a total of 180 degrees

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

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

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

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