Which transformations will produce similar, but not congruent, figures?
a. triangle pqr is reflected across the x-axis and then rotated 90° clockwise to form triangle pꞌꞌqꞌꞌrꞌꞌ.
b. triangle pqr is reflected across the y-axis and then dilated by a scale factor of 6 to form triangle pꞌꞌqꞌꞌrꞌꞌ.
c. triangle pqr is rotated 180° counterclockwise and then translated 11 units left to form triangle pꞌꞌqꞌꞌrꞌꞌ.
d. triangle pqr is rotated 90° clockwise and then reflected across the y-axis to form triangle pꞌꞌqꞌꞌrꞌꞌ.
