Question

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? a reflection across the line containing ab a rotation about point b a reflection across the line containing cb a rotation about point c

Explanation:

• Rigid transformations include translations, rotations, and reflections.
• After translating vertex \(B\) to vertex \(R\), we need to align the other vertices.
• A rotation about point \(C\) (since \(C\) and \(S\) have the same - angled markings in the triangles) will map \(\triangle ABC\) to \(\triangle QRS\) after the translation.

Answer:

a rotation about point \(C\)
