Center Line - answer - A line which defines the center of arcs, circles, or symmetrical parts. Construction Line - answer - lightly drawn lines to guide drawing other lines and shapes. Depth - answer - The measurement associated with an object's front-to-back dimension or extent of something from side to side.
