Identify row, column, square, symmetric and zero matrices
Consider the four matrices shown below
\[A = \begin{bmatrix} -7 & 3 \\ 2 & 0 \end{bmatrix}\]
\[B = \begin{bmatrix} 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 \end{bmatrix}\]
\[C = \begin{bmatrix} 2 & 7 & -6 \end{bmatrix}\]
\[D = \begin{bmatrix} 0 & 0 & 0 \\ 0 & -9 & 0 \\ 0 & -3 & 0 \end{bmatrix}\]
