two rigid transformations are used to map $delta hjk$ to $delta lmn$. the first is a translation of vertex h to vertex l. what is the second transformation?\n○ a reflection across the line containing $overline{hk}$\n○ a rotation about point h\n○ a reflection across the line containing $overline{hj}$\n○ a rotation about point k

Answer

Brief Explanations:

First, after translating vertex H to vertex L, we match the corresponding congruent parts of the triangles. The marked congruent sides and angles show that to align the rest of the triangle HJK with LMN, we need a rotation about the new position of H (which is L, equivalent to original point H in the context of the transformation sequence). This rotation will orient the triangle correctly to match ΔLMN.

Answer:

a rotation about point H
