Question

Identify the matrix transformation of ΔRST, which has coordinates R(−1, 1),S(2, −2), and T(−3, 3), for 90° rotation, clockwise. Then identify the correct vertices of the image.

Answer 1

Answer:

( 0     1  ) ( -1   2   -3)      (1   -2    3)

                                =                      R' (1, 1), S' (-2, -2), T' (3, 3)

( -1     0 ) ( 1   -2    3)      (1   -2    3)

Step-by-step explanation:

Write the x - coordinates of RST in row 1 and the y - coordinates in row 2 of the matrix.

(-1    2   -3)

(1    -2    3)

R     S     T

For a 90° rotation, clockwise, multiply the matrix by (0   1)

                                                                                      (-1   0)

Then you get your answer.
