Question

Quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line. Which line segment in the image corresponds to NO¯¯¯¯¯¯ in the pre-image?
AB¯¯¯¯¯

AD¯¯¯¯¯

CD¯¯¯¯¯

BC¯¯¯¯¯

Answer 1

Answer: CD

Step-by-step 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.

Answer 2

NO-CD
AB-LM
AD-LO
CD-NO
BC-MN
