Question

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

Explanation:

Rigid transformations preserve size/shape (translation, rotation, reflection). Dilation is non-rigid. Congruent triangles (SSS) can be mapped via rigid transformations. Likely reflection (to flip orientation) then translation (to align positions).

Answer:

reflection, then translation
