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

2. A triangle with sides of different lengths and no two angles are the same

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

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

5. The horizontal number line of a coordinate graph

6. A triangle with two equal sides and two equal angles

7. The total of two or more numbers being added

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

9. An angle that measures 180 degrees

10. Two angles whose sum equals 90 degrees

11. In a division problem - it's the number being divided

12. The distance around a figure

13. A polygon that has four sides

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