\

Square $\"\"$ vertices are $\"\"$ and $\"\"$ .

\

Write the vertex matrix for square $\"\"$ is $\"\"$ .

\

Find rotation at $\"\"$ about the origin.

\

To rotate $\"\"$ about the origin, multiply the vertex matrix by $\"\"$ .

\

Write the vertices of the image.

\

The first row represents the $\"\"$ –coordinates and the second row represents the $\"\"$ –coordinates.

\

The vertices are $\"\"$ and $\"\"$ .
