Answer:
Reflection about either the x- axis or y- axis.
Step-by-step explanation:
It is likely that the triangle shows a mirror image when it has been rotated at point C so that it matches ΔADC.
The triangles are congruent if the sides and angles are equal. The only way to effect the change is through a rotation.
In fact, two objects are said to be congruent if they can be transformed into another shape by translation, rotation, and reflection.
The resulting image is a distinct figure that can fit and match the other completely.
In this case, the triangle is rotated through 180⁰ so the resulting image is a reflection or mirror image.
