Subjects : math, 7th-grade, 8th-grade
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 polygon that has four sides






7. The horizontal number line of a coordinate graph






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






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






10. Having the same size and shape






11. A polygon with six sides.
