Answer:
second transformation is a reflection across the line containing AB
Step-by-step explanation:
The options are : a reflection across the line containing AB , a rotation about point B, a reflection across the line containing CB, a rotation about point C
The diagram is attached below
The triangle ABC is transformed to get triangle QRS
First transformation is the translation of vertex B to vertex R.
To get the same triangle QRS, the triangle to be reflected across the line AB
So second transformation is a reflection across the line containing AB
