| Drawing of an object in a three-dimensional form on a plane surface. | Perspective |
| points that are located on the horizon line and which the receding lines of a building intersect. | Vanishing point |
| Drawing that has constant angles. 30 degree’s from the horizon. Used more in mechanical engineering drawings. | Isometric drawing |
| Three types of pictorial drawings that are used as presentation drawings | Isometric, Oblique, and Perspective. |
| perspective that is commonly used for exterior views. | Two point perspective |
| represents the horizontal plane which is called the ground plane. | Ground line |
| represents the place where the ground and sky meet. The distance between the ground line and the horizon line represents the height of the observer’s eye above the ground. | Horizon line |
| Plane on which the perspective is drawn. | Picture plane |
| Location of the observers eye and therefore the beginning point of the visual rays or sight lines. | Station point |
| True length line or true height line. Established where the object touches the picture plane. | True length line |
| If a station point were moved from 20ft. to 30ft. away from the picture plane, the perspective would? | increase in size |
| One-point perspectives are well suited for? | interior views. |
| A two-point perspective has? | Two vanishing points |
| If the station point is too close to the picture plane the perspective may be spoiled because of? | Distortion |
| One may determine the closest place to stand to draw a perspective by the? | angle and position of the object |
