Detailed Solution

A matrix is said to be Orthogonal matrix if A.A^T = A^T.A = I.

A matrix is said to be Involutory matrix if and only if A² = I, where I is the n × n identity matrix.

A matrix is said to be idempotent matrix if A² = A.

A square matrix A is said to be a nilpotent matrix of degree n if Aⁿ=0
