Subjects : math, 7th-grade, 8th-grade
  • 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 triangle with one right angle

2. A polygon with six sides.

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

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

5. A parallelogram with all sides equal and congruent

6. Surface space that is measured in square units

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

11. The distance around a figure

12. The result of muliplying two or more numbers

13. A polygon with five sides

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

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

16. An eight-sided polygon

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

21. A mathematical sentence that uses an equal sign

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

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

24. An angle that measures 180 degrees

25. The value on the y-axis used to locate a point on the coordinate graph. It is the second value in an ordered pair.

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

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