**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 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**

**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**

**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.**
