Two vectors are orthogonal in vector spaces if their dot product equals zero. This means they are at a right angle to each other in the vector space.&nbsp;<\/p>\n\n\n\n<p>For instance, in a 2D plane, the vectors v=(1,0) and w=(0,1) are orthogonal because their dot product is 1\u00d70+0\u00d71=0.<\/p>\n\n\n\n<p>When dealing with matrices, orthogonality extends to matrices where columns (or rows) are orthogonal vectors. An orthogonal matrix is a square matrix whose columns and rows are mutually orthogonal unit vectors.
