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.

25. In transversals






26. The difference between x and y






27. 1-v3- 2 (90-30-60)






28. (x-y)(x-y) = (x-y)²






29. The lines that divide each angle of the triangle into two equal parts. these lines meet in a point that is the center of a circle inscribed in the triangle.






30. R²






31. (x+y)(x+y)= (x+y)²






32. All sides are equal and all of whose angles are equal. 1. can be inscribed in a circle and can be circumscribed about another circle. 2. each angle is equal to the sum of the angles divided by the number of sides 180(n-2)°/n.
