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.

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






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






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






5. Surface space that is measured in square units






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