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. The vertical number line of a coordinate graph

2. 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.

3. In a division problem - the number that an amount is divided by

4. A solid figure with two congruent and parallel circular bases

5. In a group of values - the value that occurs most often

6. A parallelogram with four right angles

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

8. A comparison of the two values of two numbers

9. The horizontal number line of a coordinate graph

10. The result of muliplying two or more numbers

11. The difference between the least and greatest values in a set of numbers

12. A quadrilateral with two pairs of congruent - parallel sides

13. A ratio that compares two different types of quantities

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

15. A solid figure that has triangles for its sides and a polygon as its base
