# 7th 8th Grade Math Vocab

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. A fraction with all common factors (other than 1) factored out of the numerator and denominator

2. A value found by ordering a group of data from least to greatest and choosing the middle value of the group.

3. The difference between the least and greatest values in a set of numbers

4. A parallelogram with four right angles

5. A polygon with five sides

6. An angle measuring more than zero degrees and less than 90 degrees

7. The ratio of a number to 100 (per one hundred); the symbol %

8. The inverse of a fraction; when multiplied by the original fraction - it results in a product that equals one

9. An eight-sided polygon

10. The result of dividing one number by another; the solution to a division problem

11. Two numbers listed in a specific order; it describes a point on the coordinate graph

12. An angle measuring more than 90 degrees and less than 180 degrees

13. An equation stating that two ratios are equal

14. Having the same size and shape

15. A number that when multiplied by itself results in the original number

17. A length that is half the diameter of a circle; the distance from the center of the circle to the circle itself

18. A solid figure with two congruent and parallel circular bases

19. The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair.

20. A quadrilateral with two pairs of congruent - parallel sides

21. In a division problem - the number that an amount is divided by

22. To make a fraction easier to work with by taking out common factors

23. A parallelogram with all sides equal and congruent

24. Figures that have the same shape but different sizes; their sides are proportional - while their corresponding angles are equal

25. A number that tells how many times the base is multiplied by itself

34. Rules that tell which steps to follow when solving an expression

35. In a group of values - the value that occurs most often

36. The sum of a group of numbers divided by the number of numbers; also known as the average

37. The amount that remains after one number has been subtracted from another

38. The distance around a circle (the perimeter of a circle)

39. A solid figure that has triangles for its sides and a polygon as its base

40. The point of intersection for two sides of a plane figure - three sides of a solid figure - or the endpoints of two rays that form an angle.

41. A mirror image of a figure shown over a line of reflection

42. A quadrilateral with one pair of parallel sides

43. A combination of numbers and variables connected by one or more operations signs
