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






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






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






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

37. A comparison of the two values of two numbers






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






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






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






41. A quadrilateral with one pair of parallel sides






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