Remember
![x^{ \frac{m}{n} }= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20)
so
![x^{ \frac{1}{2} }= \sqrt[2]{x^1}](https://tex.z-dn.net/?f=x%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%3D%20%5Csqrt%5B2%5D%7Bx%5E1%7D%20)
or √x
so

Explanation:
When applying any kind of reflections, the parallel sides will stay parallel. Check out the diagram below for an example of this.
So PQ stays parallel to RS. Also, QR stays parallel to PS.
The statement "PQ is parallel to PS" is incorrect because the two segments intersect at point P. This letter "P" is found in "PQ" and "PS" to show the common point of intersection. Parallel lines never intersect.
