Question

a composition of transformations maps δklm to δk\l\m\. the first transformation for this composition is ______, and the second transformation is a translation down and to the right. a 90° rotation about point l a 270° rotation about point l a 90° rotation about point p a 270° rotation about point p

Explanation:

1. First, analyze the relationship between $\Delta KLM$ and $\Delta K'L'M'$. A rotation about point L would keep L fixed, but L moves to L', so rotation centers L are invalid.
2. For a 90° rotation about point P, the orientation and position shift would not match $\Delta K'L'M'$. A 270° (equivalent to -90°) rotation about P correctly maps $\Delta KLM$ to $\Delta K'L'M'$, which is then translated down/right to $\Delta K''L''M''$.

Answer:

D. a 270° rotation about point P
