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

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. A half-circle

5. A triangle that contains a 90 degree angle

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

7. Two lines meeting to form right angles

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

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

10. Two angles containing a total of 90 degrees

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

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

13. One of two equal factors of a number

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

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

16. 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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

31. Two angles containing a total of 180 degrees

32. A quadrilateral that has four 90 degree angles

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

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

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

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

37. 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

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

39. Lines in the same plane that never meet

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

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

42. The top number of a fraction

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

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

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

46. 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

47. An angle that contains less than 90 degrees

48. The point equidistant from the ends of a line

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

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