What does the term "mirror" refer to in graphical communication?

The term "mirror" in graphical communication refers to the process of creating a symmetrical copy or image. This concept is often used in design and drafting to ensure that elements are visually balanced and reflect across a line of symmetry. When a design is mirrored, one side is replicated on the opposite side, producing an identical image and maintaining proportionality, which is crucial in fields such as graphic design, architecture, and product design.

In this context, symmetry is vital for aesthetic appeal and functionality, as many designs need to look cohesive and harmonious. The ability to produce mirrored images or reflections aids in visualizing designs, ensuring that they meet the desired specifications for symmetry and balance. This technique is fundamental in creating logos, layouts, and various graphical representations.

The other options relate to different drafting techniques or concepts but do not encompass the essence of mirroring within graphical communication. For example, removing parts of lines or making lines touch other shapes involves specific measures of connection and intersection rather than the concept of creating symmetry through repetition.
