Question

what information do you need to reflect an image? line of reflection counter clockwise line of rotation degree of reflection

Explanation:

Reflection of an image in geometry requires the line of reflection. It acts as a mirror - like boundary across which the image is flipped. Rotation is a different transformation, and there's no such thing as "degree of reflection" in standard geometric transformation terms. Counter - clockwise is related to rotation direction, not reflection.

Answer:

line of reflection
