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:

Rigid transformations preserve size and shape. Dilation is not a rigid - transformation. To map △ABC onto △FED, first, a rotation can be used to align the orientation of the triangles, and then a translation can be used to move △ABC to the position of △FED.

Answer:

rotation, then translation
