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

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

**3. An integer**

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

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

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

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

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

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

**10. The sum of the lengths of all the sides of a polygon**

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

**12. A four-sided polygon. the angles total 360 degrees.**

**13. A quadrilateral that has four 90 degree angles**

**14. 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**

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

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

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

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

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

**20. 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**

**21. A 5 sided polygon**

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

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

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

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

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

**27. Having all sides equal. an equilateral triangle has three equal sides**

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

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

**30. A 6-sided polygon**

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

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

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

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

**35. The digit all the way on the right of a number**

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

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

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

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

**40. 'in the same order'**

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

**42. The bottom of a fraction**

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

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

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

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

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

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

**49. A half-circle**

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