It has an equal number of rows and columns, and hence its order is of the form n × n. All the matrix operations of transpose, determinant, adjoint, inverse, and the mathematical operations of matrices apply to a square matrix also.

Orthogonal matrix is a real square matrix whose product, with its transpose, gives an identity matrix. When two vectors are said to be orthogonal, it means that they are perpendicular to each other. When these vectors are represented in matrix form, their product gives a square matrix.
