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






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






3. A polygon with five sides






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






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






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






7. Two angles whose sum is 180 degrees






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






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






10. A solid figure with two congruent and parallel circular bases






11. A number that when multiplied by itself results in the original number






12. 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.






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






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