SAT Math 1 Vocab

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. A half-circle






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






3. 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






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






5. A triangle that contains a 90 degree angle






6. A collection of all the points that are the same distance from one - central point






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






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






9. The number you get when you add a group of numbers and then divide by how many there are. also called an arithmetic mean






10. A whole numeral. there are 10 of them: 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - and 9.






11. The top number of a fraction






12. 'from now' ex. 7 years hence= 7 years from now






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






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






15. A 6-sided polygon






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






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






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






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






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






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






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






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






24. A 5 sided polygon






25. The middle number in a group






26. Two angles containing a total of 180 degrees






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






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






29. A rectangular solid with six square sides or faces. also - a number raised to the third power






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






31. 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






32. 'in the same order'






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






34. The bottom of a fraction






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






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






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






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






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






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






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






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






43. Lines in the same plane that never meet






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






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






46. Two angles containing a total of 90 degrees






47. 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






48. Two lines meeting to form right angles






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






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