Question

the triangles are congruent by the sss congruence theorem. which rigid transformation(s) can map △abc onto △fed? reflection, then dilation reflection, then translation rotation, then translation rotation, then reflection

Explanation:

Step1: Recall rigid - transformations

Rigid - transformations include rotation, reflection, and translation. Dilation is not a rigid - transformation as it changes the size of the figure.

Step2: Analyze mapping of congruent triangles

To map one congruent triangle onto another, we can use a combination of rotation, reflection, and translation. First, we can rotate one triangle to align its orientation with the other. Then, we can translate it to match the position.

Answer:

rotation, then translation
