5-36. Where are the vanishing points located? 1. On the ground line 2. On the horizon line 3. On the picture plane 4. On the front view 5-37. A 3-foot edge of an object represented on a drawing to a scale of 1"=2"-0" is parallel to the plane of projection. You should draw this edge to what size on you drawing? 1. 3/4 inches 2. 1.5 inches 3. 6 inches 4. 2 inches 5-38. A 3-foot edge of an object represented on a drawing to a scale of 1"=2"-0" is behind the plane of projection. How should you draw this edge? 1. 2. Foreshortened In true length 3. At a 2:1 scale 4. At 2/3rds full scale 5-39. A circle shown parallel to the plane of projection on a drawing in two-point perspective appears as what shape? 1. An ellipse 2. A circle 3. A parabola 4. A  hyperbola 5-40. What should you do to determine the perspective of lines and planes inclined away from the picture plane? 1. Project an auxiliary view 2. Locate their station points 3. Locate their vanishing points 4. Revolve the view toward the plane of projection 5-41. How should you transfer the measurements of a circle that is shown oblique to the plane of projection? 1. Use a set of dividers 2. Inscribe a square within the circle 3. Use a trammel 4. Circumscribe the circle with a square 5-42. How many check points should you use when transferring measurements from a circle to a surface oblique to the plane of projection? 1. Six 2. Seven 3. Eight 4. Five 5-43. You should use a square to help you in drawing circles in perspective for what reason? 1. Squares  have  transferable measurements 2. Squares eliminate the need for vanishing points, plan views, and elevation views 3. Squares are equally proportional 4. Squares project as accurate picture planes 5-44. In one-point perspective, what is the easiest way to draw circular shapes? 1. Perpendicular to the picture plan 2. Parallel to the picture plane 3. Drawing them true size 4.    Drawing them in true perspective 5-45. When you construct a perspective drawing of an object that contains inclined lines and planes, the plan and elevation serve what purpose? 1.    Measuring 2. Projecting the vanishing points 3. Locating the picture plane 4. Projecting horizon line 31
