Reflecting LMN across the horizontal line =y2, we get its image L'M'N'. Suppose LL', MM', and NN' intersect the line of reflection at S, T, and U as shown below.

Complete the following.
(a)Select all that apply.

LL', MM', and NN' are each perpendicular to the line of reflection.

LL' is parallel to MM', and LL' is perpendicular to NN'.

LL', MM', and NN' are parallel to each other.

None of the above
(b)Suppose each pair of segments below have the same length.
Find each length.
==LSL'Sunits
==MTM'Tunits
==NUN'Uunits
(c)Choose the correct statement about the reflection.

Each side of the original figure is perpendicular to its image.

The line of reflection is the perpendicular bisector of each segment joining a point and its image.

The line of reflection is neither parallel nor perpendicular to each segment joining a point and its image.

The line of reflection is parallel to each segment joining a point and its image.
