Subjects : math, common-core
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 ray that divides an angle into two congruent angles






2. An angle that measures less than 90 degrees






3. The set of all points in a plane that are the same distance from a given point called the center






4. Two angles whose measures have a sum of 90






5. Angles that have the same measure






6. If B lies on AC - then AB + BC = AC.






7. Has no dimension. It is usually represented geometrically by a small dot. Named by a capital letter. Read: point A.






8. A line - segment - ray - or plane that intersects AB at its midpoint is a bisector of AB.






9. [(x1+ x2)/2 - (y1+ y2)/2]






10. An angle greater than 180 degrees (but less than 360)






11. An arc of a circle whose measure is less than 180 degrees.






12. An angle that measures 90 degrees






13. Point M is the midpoint of AB if M lies on AB and AM = MB.






14. The number of degrees in an angle






15. An angle that measures 180 degrees






16. One endpoint and extends indefinitely in one direction






17. D = v[( x2 - x1)






18. Point M is the midpoint of AB if M lies on AB and AM = MB.






19. An angle greater than 180 degrees (but less than 360)






20. Cut into two equal pieces






21. Two angles whose measures have a sum of 180






22. An angle between 90 and 180 degrees






23. A fraction of a circle's circumference






24. A ray that divides an angle into two congruent angles






25. Part of a line with two endpoints






26. Part of a circle / part of a circle named by its endpoints






27. Points outside of the angle






28. In a right triangle - the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. a squared + b squared = c squared






29. Common endpoint of an angle






30. Points on the same plane






31. An unbounded two-dimensional shape - represented by a capital script letter -






32. The distance between the endpoints of a segment.






33. Extends in one dimension indefinitely. It is usually represented by a straight line with arrowheads to indicate that the line extends without end in two directions.






34. Two rays with common endpoints that form a line.






35. An angle between 90 and 180 degrees






36. D = v[( x2 - x1)






37. An angle that measures 180 degrees






38. Points on the same line






39. In a right triangle - the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. a squared + b squared = c squared






40. Region bounded by two radii of the circle and their intercepted arc






41. If two planes intersect then their intersection is a line






42. Angle that measures between 90






43. Formed by two rays (sides) with the same endpoint called vertex






44. Points inside of the angle






45. In the interval






46. Intersecting lines or segments will meet at a point






47. Points outside of the angle






48. Coplanar lines that intersect to form a right angle.






49. In the interval






50. Has no dimension. It is usually represented geometrically by a small dot. Named by a capital letter. Read: point A.
