**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.

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

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

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

**4. One of two equal factors of a number**

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

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

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

**8. A line connecting one point on a circle with another**

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

**10. An angle that contains less than 90 degrees**

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

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

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

**14. Two angles sharing one common side and a common vertex**

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

**16. 'in the same order'**

**17. 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**

**18. 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**

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

**20. One after the other - without skipping. numbers in order.**

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

**22. The top number of a fraction**

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

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

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

**26. Two lines meeting to form right angles**

**27. A 5 sided polygon**

**28. The number you get when you add two or more numbers**

**29. A triangle that contains a 90 degree angle**

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

**31. A half-circle**

**32. A triangle having at least two equal sides and two equal angles**

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

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

**36. 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**

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

**38. A 6-sided polygon**

**39. The number you get when you multiply two numbers**

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

**41. 'from now' ex. 7 years hence= 7 years from now**

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

**43. The middle number in a group**

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

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

**46. Two angles containing a total of 180 degrees**

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

**48. The number you get when you divide one number into another number**

**49. The number you get when you subtract one number from another.**

**50. Two angles containing a total of 90 degrees**
