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 closed plane figure formed by the plane section of a right angled cone.

2. A term used to describe the creation of an exact part replicated on the other side of a drawn axes.

3. The line where two pieces of material come together.

4. A three-sided polygon.

5. The lines or points belonging to the same line or an extension of that line.

6. An effective visual means of communication that utilizes freehand drawing. A collection of freehand drawings that communicate an idea. There are three types: program - design - and thumbnail.

7. A linear measurement that shows the extents of something - such as width - height - or length.

8. A term used to describe two things having the same value or size.

9. Any physical portion of an object - such as a hole or fillet.

10. A right angle projection wherein the views on a drawing are drawn at right angles to one another.

11. In drawing software - a term describing the shortening of a line or removal of material in a drawing.

12. A closed geometric figure in a plane formed by connecting line segments endpoint to endpoint with each segment intersecting exactly two others. Polygons are classified based on the number of line segments used - such as triangle - quadrilateral - pen

13. In drawing software - a term describing the reorientation of a drawing.

14. The features of an object projected onto a reference plane - such as the front - top - right and side views.

15. The plane that is created in order to slice through a part or assembly to show the interior details.

16. A special type of quadrilateral with its opposite sides parallel to each other - referred to as a parallelogram - and with all of its angles as right angles.

17. (1) Computer Aided Drawing (2) The use of a computer to create drawings.

18. A perfectly round object where all points are equidistant from a fixed point.

19. The line drawn from a detail to the dimension line on a drawing to show the area of the measurement.

20. In drawing software - parts of a two-dimensional drawing that attach surfaces together when the pattern is folded into a three-dimensional shape.

21. A four-sided polygon with equilateral sides and 90-degree interior angles.

22. A file in the listing of the files stored in memory usually on a hard disk of a computer.

23. A helix or conical shape that is found on the external shaft or the internal surface of a cylindrical hole.

24. The line drawn from a detail to the dimension line on a drawing to show the area of the measurement.

25. A process used to change details in a drawing after initial creation.

26. The use of computer software applications that allows the user to visualize an idea in a three-dimensional format.

27. A process used to change details in a drawing after initial creation.

28. Of or exhibiting equality in dimensions or measurements.

29. A curved surface formed at the interior intersection of two or more surfaces of an object.

30. (1) A hole consisting of two depths so that the top of the head of an inserted bolt or screw will be flush with the outside surface. (2) A bit for enlarging the upper part of a hole.

31. The process of stretching or lengthening the measurement of a detail on a drawing.

32. A closed curve with coplanar points at the same distance from the center point.

33. A three-sided geometric figure having all sides equal.

34. A right angle projection wherein the views on a drawing are drawn at right angles to one another.

35. The line drawn from a detail to the dimension line on a drawing to show the area of the measurement.

36. The wedge shaped mark on a drawing used to terminate the dimension line.

37. A term describing a detail that is upright or perpendicular to the horizon.

38. A detail created that forms an angle at the intersection of two planes.

39. A term describing parts or features being equal distances apart at every point.

40. In a computer-aided drawing program - a feature created by adding depth to a sketched profile of an object.

41. A closed plane figure formed by the plane section of a right angled cone.

42. The two points that are fixed together with the use of a constraint.

43. The limitation of measurement that is placed on a part of a product.

44. A line parallel to the horizon.

45. A polygon that has four-sides.

46. A three-sided geometric figure having all sides equal.

47. The use of computer software applications that allows the user to visualize an idea in a three-dimensional format.

48. A drawing that describes more fully the attributes of a part.

49. A line parallel to the horizon.

50. The plane that is created in order to slice through a part or assembly to show the interior details.
