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.

4. A quadrilateral with one pair of parallel sides






5. A polygon with five sides






6. A line segment that passes through the center of a circle and has its endpoints on the circle






7. A triangle that has three equal sides and three equal angles






8. The point of intersection for two sides of a plane figure - three sides of a solid figure - or the endpoints of two rays that form an angle.






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