The line that defines the edge of a shape is called the: Group of answer choicesoutline.contour.implied line.volume.scale.

The correct answer is contour.

Explanation:

In the context of art and design as well as geometry, the term “contour” specifically refers to the outline or shape of an object. It is used to define how an object appears to the viewer by emphasizing its edges and boundaries.

1. Outline generally describes the line that outlines a shape but may imply less detail than contour, which more effectively captures the essence of the shape through its curves and details.

2. Implied line refers to a line that is not physically drawn but is suggested through other elements, often leading the viewer’s eye or indicating a direction, rather than defining a physical edge.

3. Volume refers to the three-dimensional aspect of an object, which is not relevant when discussing the defining edges or outlines.

4. Scale pertains to the relative size of an object in comparison to other objects or the environment, which is also not directly related to the concept of edges.

In summary, when defining the edge of a shape, "contour" is the most appropriate term among the options provided.
