\

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

\

Vertices are dilated such that its perimeter is three times the original perimeter.

\

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

\

If the perimeter of the image is three times that of the preimage, then the length of the sides of the

\

figure will be triple the measure of the original lengths.

\

Multiply the vertex matrix by the scale factor $\"\"$ .

\

$\"\"$ .

\

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 $\"\"$ .

Observe the graph:

\

$\"\"$ and $\"\"$ are similar both has same shape.

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

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