Answer: CD
Explanation:
- Reflection is a rigid transformation which always create a congruent image of the original image or pre-image.
If quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line.
then both the quadrilaterals are congruent.
To find the line segment in the image corresponds to NO in the pre-image, just check the order of the letters in the name of quadrilaterals.
[ Also, In reflection image and its pre-image are equidistant from the line of reflection]
hence, CD is the line segment in the image corresponds to NO in the pre-image.
