The first two-steps of rigid transformation required to map ΔHJK to ΔLMN are: translation and rotation. Therefore, the correct answer to the question is: B. a rotation about point H
A rigid transformation is a process in which the size and orientation of a given shape is adjusted so as to produce its image. This may involve either increasing or decreasing any or all dimensions of the shape.
Some methods required in rigid transformation are: rotation, reflection, translation and dilation. In rigid transformation, some processes involve the combination of two or more methods so as to produce the required image.
In the given question to map ΔHJK to ΔLMN, vertex H has to be translated first to vertex L. Then the second transformation required is a rotation about point H.
Therefore, the second transformation to map ΔHJK to ΔLMN is option B. a rotation about point H
