Ответ:
B. reflection
Explanation:
Rigid transformations are methods involved in changing the dimensions or orientation of a given figure. The methods are; dilation, rotation, translation and reflection.
Reflection is the process in which a given figure is turned or flipped with respect to a point or line of reference.
In the given question,
ΔDEF ≅ ΔD'EF' (Side-Side-Side congruence property)
This implies that ΔDEF was reflected about point E to produce ΔD'EF'. Thus the required rigid transformation is reflection.
Ответ:
The answer to the question is A) an atom.
