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. Two angles containing a total of 180 degrees






2. The bottom of a fraction






3. A triangle that contains a 90 degree angle






4. The sum of the lengths of all the sides of a polygon






5. A half-circle






6. An integer






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






8. The 'length' of a circle - measured from one point then all the way back to that point






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






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






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






12. A 5 sided polygon






13. The amount of space inside a two-dimensional (flat) object. measured in square units






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






15. A quadrilateral that has four 90 degree angles






16. The number you get when you multiply two numbers






17. With two fractions expressed as an inequality - to multiply the numerator of one fraction times the denominator of the other






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






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






20. An angle that contains less than 90 degrees






21. A whole number that can be either positive - negative - or zero.






22. Lines in the same plane that never meet






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






24. 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






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






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






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






28. The top number of a fraction






29. A 6-sided polygon






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






31. A line connecting one point on a circle with another






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






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






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






35. The line connecting the vertices of two opposite angles of a quadrilateral.






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






37. The middle number in a group






38. Number that are multiplied together. the ones for 6 are 1 - 2 - 3 - and 6.






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






40. 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






41. 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






42. One of two equal factors of a number






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






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






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






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






47. The place where the x axis frosses the y axis. usually referred to as the point (0 -0)






48. Two lines meeting to form right angles






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






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