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. An angle that measures 180 degrees






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






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






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






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

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






24. A combination of numbers and variables connected by one or more operations signs






25. The value on the x-axis used to locate a point on the coordinate graph. It is the first value in an ordered pair.

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






32. A number that tells how many times the base is multiplied by itself






33. A drawing of an object that is different in size (usually smaller than the original) but keeps the same proportions






34. 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.
