# 7th 8th Grade Math Vocab

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. The vertical number line of a coordinate graph

2. 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.

3. In a division problem - the number that an amount is divided by

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

13. A ratio that compares two different types of quantities

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

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

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

50. A fraction with all common factors (other than 1) factored out of the numerator and denominator
