To move triangle ABC to triangle EGH and show that they are congruent, we need to perform the following sequence of transformations:
1. Reflection over the x-axis: This will reflect triangle ABC to its mirror image below the x-axis.
2. Translation: This is indicated by the phrase "then a translation of", followed by an empty space. The specific translation vector is missing from the description, so we cannot determine the exact translation that needs to be performed.
Therefore, the correct answer would be reflection over the x-axis, followed by an unknown translation.
