Subjects : sat, math
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 number you get when you add a group of numbers and then divide by how many there are. also called an arithmetic mean






2. Comparison of two or more numbers - expressed in lowest terms






3. A unit of measure used to describe the size of an angle or part of a circle. a complete circle has 360 degrees






4. The number you get when you add two or more numbers






5. A section of a circle - also known as a little curved thing






6. Having all sides equal. an equilateral triangle has three equal sides






7. The 'steepness' of a line. determined with a fraction: rise/run






8. One after the other - without skipping. numbers in order.






9. A number or group of numbers represented by a letter or symbol. the value can vary depending on the mathematical relationship defined for it






10. The digit all the way on the right of a number

11. An arithmetic or algebraic expression that has some value on the left and some value on the right






12. Triangles that have the same angles and are the same size. the three angles and three sides of one triangle is equal to the three angles and three sides of the other






13. Formed by two lines that either intersect (cross each other) or start from the same point. the opening is measured in degrees and can be thought of as a fraction of a circle's 360 degrees






14. A quadrilateral that has four 90 degree angles and four equal sides. also - a number raised to the second power.






15. An angle whose measure is more than 90 degrees and less than 180 degrees






16. The bottom of a fraction






17. The point where two lines meet to form part of a polygon






18. The longest line you can draw from one point in a circle to another (the longest chord). The diameter is two times the length of the radius






19. Two angles containing a total of 90 degrees






20. The distance from the center of a circle to any point on the circle






21. A quadrilateral whose opposite sides are both parallel and equal in length and whose opposite angles are equal






22. An integer






23. A triangle having at least two equal sides and two equal angles






24. 'in the same order'






25. A number whose only positive whole number facotrs are 1 and itself.






26. Two triangles with exactly the same three angles. Similar triangles do not have to be the same size.






27. The mathematical chance of something happening. can be expressed as a fraction - ratio - decimal - or percent.






28. Lines in the same plane that never meet






29. A three sided polygon. the angles of a triangle total 180 degrees






30. A Greek letter used to represent the relationship between the radius of a circle and its circumference and area.






31. In a right triangle - the longest side (the side opposite the right angle)






32. Including the two extremes. the integers from 1 to 5 inclusive are 1 - 2 - 3 - 4 - and 5.






33. One of two equal factors of a number






34. The product of two or more whole numbers. 40 is this of 5 because 5×8=40. therefore 40 is also this of 8






35. The point equidistant from the ends of a line






36. An angle that contains less than 90 degrees






37. A quadrilateral that has four 90 degree angles






38. Two angles sharing one common side and a common vertex






39. The amount of space contained in - or occupied by - a solid figure. expressed in in cubic units.






40. To cut exactly in half. a line that does this to a 70 degree angle divides it into two 35 degree angles






41. Formula used to describe the relationship among the lengths of the sides of a right triangle






42. The number left over after you've divided one number into another number






43. The line perpendicular to the base of a polygon - or the length of that line.






44. The symbol (v) that tells you to find the square root of a number






45. A 6-sided polygon






46. A solid whose base and top are identical parallel circles. unless otherwise stated - sides are always perpendicular to bases






47. The number you get when you divide one number into another number






48. A half-circle






49. The number you get when you subtract one number from another.






50. A 5 sided polygon
