Final answer:
The outline of the face, head, and figure seen in a side view is referred to as the profile. This term is used in the context of visual arts to describe the side view of a person's face or body. Contour lines are used in drawing to outline and create the illusion of three dimensions and form.
Step-by-step explanation:
The outline of the face, head, and figure seen in a side view is known as the profile. When observing a drawing from a side view, such as the left side of the head and how the brain would sit beneath the skull, or considering the direction of light that creates a silhouette, the term 'profile' represents this side perspective. In the context of art and drawings, the contour lines are used to delineate surface features and differences, providing a sense of form. These lines can create the illusion of three dimensions and are essential for shading. An example of contour usage is visible in the representation of the horsemen, where their outlines are clearly defined by contour lines, creating a sense of form and shading.
It's important to note the use of silhouettes in art, which occurs when a shape is outlined and filled in with a solid color, usually black, against a lighter background, such as the silhouette of a weather vane against the sky.
