Question

problem #2 - unit 1 (mild)
which sequence of transformations maps abcd onto abcd and then maps abcd onto abcd?

1. a reflection followed by a rotation
2. a reflection followed by a translation
3. a translation followed by a rotation
4. a translation followed by a reflection

Explanation:

First, observe the transformation from ABCD to A'B'C'D'. The orientation of the rectangle has not changed, just its position, which indicates a translation. Then, when going from A'B'C'D' to A''B''C''D'', the orientation has changed, which is characteristic of a reflection.

Answer:

1. a translation followed by a reflection
