Two rigid transformations are used to map abc to qrs. the first is a translation of vertex b to vertex r. what is the second transformation?

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

a = 11 : 4

b = 38

c = 1 for every 6

abde or 1,2,4, 5 is the answer
