Etymology and History:

The word "diagonal" originates from the Greek "diagonios," meaning "from angle to angle," derived from "dia" (through) and "gonia" (angle). It evolved through Latin "diagonalis" and entered English in the 16th century. In Thai, "ทแยง" has roots in ancient geometric concepts influenced by Indian and Chinese traditions, adapting to modern usage in the 20th century with Western influences.

Literary References:

• From Euclid's "Elements" (ancient Greek text): "A diagonal is a line joining two non-adjacent vertices of a polygon." This foundational reference underscores its mathematical origins.
• From modern literature, in F. Scott Fitzgerald's "The Great Gatsby": "The eyes of Doctor T. J. Eckleburg are blue and gigantic—their retinas are one yard high. They look out of no face, but, instead, from a pair of enormous yellow spectacles which pass over a non-existent nose." While not directly using "diagonal," interpretations often describe the billboard's angles as diagonal, symbolizing societal oversight.
