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






2. A solid figure that has two congruent - parallel polygons as its bases. Its sides are parallelograms.






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






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






5. A parallelogram with all sides equal and congruent






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






7. An eight-sided polygon






8. Two numbers listed in a specific order; it describes a point on the coordinate graph






9. A ratio that shows the cost per unit of measure






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






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






12. A parallelogram with four right angles






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






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

24. An angle that measures 180 degrees






25. The horizontal number line of a coordinate graph






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






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






28. A value found by ordering a group of data from least to greatest and choosing the middle value of the group.






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






30. An angle measuring more than zero degrees and less than 90 degrees
