Question

Quadrilateral LMNO is reflected over the line as shown, resulting in quadrilateral CDAB. Given the congruency statement LMNO ≅ CDAB, which segment corresponds to ML?

Answer 1

It would be DC. 
LMNO
CDAB

If you have ML, you go reverse with the corresponding points. DC.

Answer 2

Answer: Segment DC corresponds Segment ML.

Step-by-step explanation:

Given: Quadrilateral LMNO is reflected over the line as shown, resulting in quadrilateral CDAB.

Given the congruency statement LMNO ≅ CDAB.

We know that the corresponding sides and angles of two congruent polygons are equal.

If  LMNO ≅ CDAB

⇒∠L corresponds ∠C  [First letters of each name]

∠M corresponds ∠ D.   [Second letters of each name]

⇒ Segment LM corresponds Segment CD

i.e.  Segment ML corresponds Segment DC.
