Asymmetry- Symmetry in which both halves of a composition are not identical. Also referred to as informal balance. Cabinet Pictorial- Oblique pictorial where depth is represented as half scale compared to the height and width scale. Cartesian Coordinate System- A rectangular coordinate system created by three mutually perpendicular coordinate axes, commonly labeled X, Y, and Z. Cavalier Pictorial- Oblique pictorial where height, width, and depth are represented at full scale. Center Line- A line which defines the center of arcs, circles, or symmetrical parts. Centroid- A 3D point defining the geometric center of a solid. Circumscribe- 1. A triangle located round a polygon such as a circle. 2 To draw a figure around another, touching it at points but not cutting it. Construction Line- lightly drawn lines to guide drawing other lines and shapes. Depth- The measurement associated with an object’s front-to-back dimension or extent of something from side to side. Dimension- A measurable extent, such as the three principal dimensions of an object is width, height, and depth. Ellipse- A regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points is constant, or resulting when a cone is cut by an oblique plane which does not intersect the base.
