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.
1. A polygon with six sides.






2. A comparison of the two values of two numbers






3. The sum of a group of numbers divided by the number of numbers; also known as the average






4. The horizontal number line of a coordinate graph






5. A triangle with sides of different lengths and no two angles are the same






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






7. The distance around a figure






8. Three or more line segments in a plane that forms a closed figure. The line segments never cross but meet at their endpoints.






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






10. The total of two or more numbers being added






11. Two angles whose sum is 180 degrees






12. The ratio of a number to 100 (per one hundred); the symbol %

15. One of the four regions formed by the intersection of the axes of a coordinate graph






16. The amount that remains after one number has been subtracted from another






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






18. 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.

26. An angle that measures 180 degrees






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






28. Figures that have the same shape but different sizes; their sides are proportional - while their corresponding angles are equal
