Prove matrix is orthogonal

WebbOrthogonal 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. Webb4. A square matrix Ais said to be orthogonal if ATA= I. Show that if a matrix is orthogonal and triangular, it must be diagonal. What are the diagonal entries? It follows from the de nition of orthogonality that A 1 = AT. Recall that the inverse of a lower triangular matrix must also be lower triangular. Thus, AT is both lower and
