Question

the image of parallelogram pqrs after a reflection across wy is parallelogram pqrs. rr = 12. what is the length of rz? 18 12 3 6

Explanation:

Step1: Recall reflection property

In a reflection, the line of reflection is the perpendicular - bisector of the segment joining a point and its image. So, if $RR' = 12$, then $RZ=\frac{RR'}{2}$.

Step2: Calculate length of RZ

$RZ=\frac{12}{2}=6$

Answer:

6
