Orthogonal Line Definition
The word orthogonal came from the Greek term ‘orthos’ meaning upright and ‘gonia’ meaning angle. According to classical Latin, the term orthogonium originally signified a rectangle. Later, it was used to represent a right triangle. During the 12th century, the term orthogonalis came into effect which meant a right angle or something related to it. Orthogonality is generalized in mathematics, science, and engineering. It is a graphical representation that demonstrates the relation between two lines angled perpendicular to each other. Several mathematical relations like linear algebra equations used this concept to describe non-overlapping or independent objects. In paintings, orthogonal lines appear to meet each other as they withdraw toward the vanishing points on the horizon.
