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






2. A 6-sided polygon






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






4. A 5 sided polygon






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






6. An angle that contains less than 90 degrees






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


8. A quadrilateral that has four 90 degree angles






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






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






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






12. The middle number in a group






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






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






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






16. A half-circle






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






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






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






20. The number you get when you multiply two numbers






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






22. The top number of a fraction






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






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






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






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






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






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






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






30. The point equidistant from the ends of a line






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






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






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






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






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






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






37. 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






38. An integer






39. Two angles containing a total of 90 degrees






40. 'in the same order'






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






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






43. Lines in the same plane that never meet






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






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






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






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






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






49. 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






50. The bottom of a fraction
