Question

1. what combination of transformations is shown below?rotation, then translationtranslation, then rotationrotation, then reflectiontranslation, then reflection

Explanation:

1. First, observe shape 1 (purple) transformed to shape 2 (light blue): this is a translation (slide) upward, with no rotation or reflection, as the shape's orientation and mirroring stay identical.
2. Next, observe shape 2 (light blue) transformed to shape 3 (green): this is a rotation (turn), as the shape's orientation has changed, and it is not a mirror reflection of shape 2.
3. The sequence matches the option "translation, then rotation".

Answer:

translation, then rotation
