the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r = \left[\begin{array}{cc}-1& 0\\0& 1\ \end{array}\right]

transformed matrix can be obtained by multiplying the given matrix by r:

\left[\begin{array}{cc}-1& 0\\0& 1\ \end{array}\right] \left[\begin{array}{cccc}0& 0& 3& 3\\0& 3& 3& 0\\ \end{array}\right]

=\left[\begin{array}{cccc}0& 0& -3& -3\\0& 3& 3& 0\\ \end{array}\right]

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)

The vertices of a rectangle are given in the columns of the matrix . if is found to perform a transf
