To find: The coordinates of the vertices after the given dilation and then graph. Then determine the coordinates and the vertices of the image and graph the pre-image and the image.
Answer to Problem 18PPS
The coordinates of the vertices is
Explanation of Solution
Given:
The given vertices are
Calculation:
Consider the vertices of the
Consider the vertices are dialled so that the perimeter is twice the original perimeter.
Multiply the vertex matrix by the scale factor
Thus, the coordinate of the vertices of the image is
The graph for the image and the pre-image is shown in Figure 1
