Orthogonal
Definition of Orthogonal
Two lines are orthogonal if they are at right angles to each other.
For example, the \(x\) and \(y\)-axes are orthogonal, and the sides of a right-angled triangle (other than the hypotenuse) are orthogonal.
Another word for "orthogonal" is "perpendicular".
There are also concepts of orthogonality for three-dimensional shapes and in other fields of mathematics.
