Question

what combination of transformations is shown below? grid with three labeled shapes (1, 2, 3) and four multiple - choice options: reflection, then rotation; rotation, then reflection; rotation, then translation; reflection, then translation

Explanation:

First, shape ① is reflected over a vertical line to get shape ②. Then, shape ② is rotated clockwise around a common vertex to get shape ③. This matches the sequence "reflection, then rotation".

Answer:

reflection, then rotation
