Answer:

∠E corresponds to ∠A .

Step-by-step explanation:

Given: Triangle ABC is the result of a 180° rotation of triangle EFG about point D.

To find: Which angle in the image corresponds to ∠E in the pre-image?

Solution : We have a triangle ABC which is pre image of EFG at rotaion of 180°.

By the rotation rule of 180°. (x.y) ----> (-x,-y).

Therefore , ∠E corresponds to ∠A .
