# 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.

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

7. The result of muliplying two or more numbers

8. A polygon with five sides

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

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

21. A comparison of the two values of two numbers

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

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

24. One of the four regions formed by the intersection of the axes of a coordinate graph

25. Three or more line segments in a plane that forms a closed figure. The line segments never cross but meet at their endpoints.

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

42. A parallelogram with all sides equal and congruent

43. 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.

44. An eight-sided polygon

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