two rigid transformations are used to map △hjk to △lmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k

Answer

Brief Explanations:

A translation moves a figure without rotation or reflection. After translating vertex H to vertex L, to map the rest of the triangle correctly, we need to rotate the triangle about point H so that the other vertices match up with the corresponding vertices of the target triangle. A reflection across the lines containing HK or HJ would change the orientation in a way that is not consistent with the mapping, and rotating about point K would not align the triangles as needed after the translation of H to L.

Answer:

a rotation about point H
