Asequence of transformations maps ∆abc to ∆a′b′c′. the sequence of transformations that maps ∆abc onto ∆a′b′c′ is a followed by a .

The ABC sequence of points is clockwise in both figures, so there will be an even number of reflections or a rotation.

Rotation 90° clockwise about the point (-3, -3) would make the required transformation, but that is not an option. An equivalent is ...
   • reflection across the line x = -3
   • reflection across the line y = x

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
