$\"\"$

\

Vertices of $\"\"$ are $\"\"$ and $\"\"$ .

\

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

\

Graph:

\

Plot the points $\"\"$ and $\"\"$ and connect the points to form $\"\"$ .

\

Plot the points $\"\"$ and $\"\"$ and connect the points to form $\"\"$ .

\

Observe the graph:

\

$\"\"$ and $\"\"$ are similar, both has same shape and rotate about $\"\"$ the origin. $\"\"$

\

Coordinates of the vertices of the images are $\"\"$ and $\"\"$ .

Graph the $\"\"$ and $\"\"$ is
