Questions: Two rigid transformations are used to map Δ HJK to triangle LMN. The first is a translation of vertex H to vertex L. What is the second transformation?

Solution Steps

The first transformation is given as a translation of vertex H to vertex L. This means that the entire triangle ΔHJK is shifted so that point H coincides with point L.

After translating H to L, the triangle ΔHJK will be positioned such that H is now at L. We need to determine the second transformation that will map the translated triangle to ΔLMN.

To map the translated triangle to ΔLMN, observe the orientation and position of the triangles. The triangles are congruent and similarly oriented, suggesting a reflection or rotation. Given the options, the correct transformation is a rotation about point K to align the triangles.
