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. An equation stating that two ratios are equal






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






4. A polygon with six sides.






5. A parallelogram with all sides equal and congruent






6. An angle measuring more than 90 degrees and less than 180 degrees
