kohtisuuntautunut

Kohtisuuntautunut is a Finnish term that translates to "perpendicular" or "orthogonal" in English. It is primarily used in geometry to describe the relationship between two lines, planes, or vectors that intersect at a right angle (90 degrees).

In two-dimensional geometry, two lines are considered kohtisuuntautunut if they cross each other at a 90-degree angle. This means the angle formed at their intersection point is precisely that of a square corner. Similarly, in three-dimensional space, two planes are kohtisuuntautunut if they intersect at a right angle.

The concept extends to vectors as well. Two vectors are kohtisuuntautunut if their dot product is zero. This property is fundamental in linear algebra and has wide-ranging applications in physics and engineering, such as in defining coordinate systems and analyzing forces. The term emphasizes a precise, mutually perpendicular orientation.
