The word "Pentagraph" is derived from the combination of two Greek roots: "penta", meaning "five", and "graph", meaning "to write" or "drawing". When combined, "pentagraph" refers to a device or instrument that writes or draws five times the size of the original. The "pentagraph" was historically used in drafting and copying, allowing for enlarging or reducing an image while maintaining proportional accuracy.
