Answer 1

Answer:

A square matrix A is Said to be an orthogonal

matrix if

A²= A This is true or felse

Is false

Answer 2

Answer:

Step-by-step explanation:

Consider a matrix A of 3×3 order.

Now,

A

′

is the transpose matrix of matrix A.

We know that,If,

A.A

′

=I

Then , matrix A is orthogonal matrix.

Hence, this is the answer.
