geometryof or involving right angles; at a right angle."Two vectors are orthogonal if their dot product is zero."Similar:perpendicular
Orthogonal is a term used in various areas of math, typically referring to a concept involving right angles.
In geometry, two lines are orthogonal if they intersect at a right angle. This concept extends to higher dimensions as well, where two lines are orthogonal if they are at right angles to each other.
In linear algebra, two vectors are considered orthogonal if their dot product is zero.
In geometry, two lines or planes are said to be perpendicular if they intersect at a right angle (90 degrees).
A vector is a mathematical object represented by an ordered list of numbers called components, which define its magnitude and direction in a multidimensional space.
