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 eight-sided polygon






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






3. The distance around a figure






4. A parallelogram with all sides equal and congruent






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






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






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






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