It is called its bounds. In the case of 2 dimensional objects, it is part of the perimeter.
It is an apothem line that connects the center of a polygon to the center of an outer side.

The line drawn to show the edge and surface ridges of an object is called a contour line. Contour lines represent the shape and form of an object, illustrating its three-dimensional qualities on a two-dimensional surface. These lines help convey depth and detail, allowing viewers to understand the object's structure and contours effectively.
In art, a line drawn to indicate the edge and surface ridges of an object is called a "contour line." Contour lines define the shape and form of an object, creating a sense of depth and dimension by following its outline and features. They are essential in both drawing and painting for capturing the volume and structure of subjects.
A line that is drawn to show the edge and surface ridges of an object is typically referred to as an "outline" or "contour line." This line helps define the shape and form of the object, providing visual clarity and depth. In art and design, contour lines are essential for conveying three-dimensionality on a two-dimensional surface. They guide the viewer's eye and enhance the understanding of the object's structure.
A margain could be drawn on any edge of a paraghraph.
The outer edge means the furthest most point from the center. The outer edge is usually the end of the object before the dropping off point.
The line that forms the edge of a figure is an edge line. Which forms the figure the has been drawn. You use this line to define a drawing or a figure.
