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 that has four sides






2. The total of two or more numbers being added






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






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






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






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






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






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. The result of dividing one number by another; the solution to a division problem






10. A polygon with five sides






11. A triangle with one right angle






12. An angle that measures 180 degrees






13. The inverse of a fraction; when multiplied by the original fraction - it results in a product that equals one






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






15. 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.






16. A mirror image of a figure shown over a line of reflection






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






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






19. A line segment that passes through the center of a circle and has its endpoints on the circle






20. A parallelogram with all sides equal and congruent






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






22. A triangle with two equal sides and two equal angles

39. Surface space that is measured in square units






40. The result of muliplying two or more numbers






41. An eight-sided polygon
