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

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

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

4. The distance around a figure
