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. x(y+z)






2. Have two equal sides and two equal angles formed by the equal sides and the unequal side.






3. y years from now






4. Diagonals divide into 6 equilateral triangles - the sides are equal to the sides of the ________. if inscribed in a circle - the length of each side is equal to the length of the radius of the circle.






5. Angle whose sides are two chords. The vertex of the angles lies on the circumference of the circle. The number of degrees of the angle is equal to 1/2 the intercepted arc






6. /100 (the ______ number over 100)

10. x less than y






11. The point where the line crosses the y-axis - x will always = 0 in this case






12. (x-y)(x-y) = (x-y)²






13. The increase from x to y






14. Between 180° and 360°






15. x²






16. ?






17. The case where the two equations are equivalent (just two different forms of the same mathematical relation). Any point that satisfies either of the equations - automatically satisfies both






18. R²






19. 1/2d






20. A closed plane whose sides are straight lines. The sum of the angles is equal to 180(n-2) - where n is the number of sides.






21. Ax= by + C






22. Area= 1/4s² v3 perimeter= 3s altitude= 1/2s v3






23. If ?B > ?A - then






24. Is drawn from the vertices perpendicular to the opposite sides. The lengths of these lines are useful in calculating the area of the trinagle since the area of the triangle is 1/2bh and the height and the _____are the same.






25. N= number of objects (order matters!!!) k= rate at a time nPk= n!/(n-k)! (remember to cancel common numbers)






26. 1-1-1 (60-60-60)






27. C²= a²+b² and angle x and y are equal to 90°






28. Angles directly across each other are equal






29. A collection of anything - numbers - letters - objects - etc. written within brackets { } two are equal if they contain the same elements.(order does not matter)






30. ? if a side is equal to b side then - the opposite corresponding angles are






31. Integer is divisible by 2






32. 2k + 1






33. Area= 1/2?r2 length= 1/2?d= ?r perimeter= d(1/2? +1)
