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.

2. A parallelogram with four right angles






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






4. The result of muliplying two or more numbers






5. A comparison of the two values of two numbers






6. Two angles whose sum is 180 degrees






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

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






10. A quadrilateral with one pair of parallel sides






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