Given:
The triangle A'B'C' is the image of the triangle ABC
To find the type of translation, we will use the coordinates of the points C and C' to find the rule
so, the coordinates of point C = (2, 2)
The coordinates of point C' = (-2, 2)
so, the rule of the translation will be:
If we apply the rule to points A and B, it will be correct
This rule represents the reflection over the y-axis
So, the answer will be:
Reflection across the y-axis
