Step-by-step explanation:
First we have to see that there's a first transformation from triangle ABC to triangle A'B'C'. This first transformation is a translation. Since the units are not shown in the graph I can only tell the direction of the translation: it's a translation to the right and down (more units to the right than down).
Then there's a final transformation from triangle A'B'C' to triangle A''B''C'', which is a reflection over the y-axis
Answer:
0. Translation to the right and down
,
1. Reflection over the y-axis
