the second law states that the incident ray, the reflected ray, and the normal all lie in the same plane.
-What can I use to support that this is true?

Place a mirror on a table so that the reflective surface is perpendicular to the table top.
Place a book on the table as well, on end and perpendicular to the mirror, so that the mirror and book form a T shape. Leave a small gap between the book and the mirror's surface.
Place a small standing object, like a marker, on one side of the book/mirror set up.
Look through the mirror on the other side of the book so that you can see the image of the marker.
The book acts as the normal line, the incident ray is the ray of light from the marker to the mirror and the reflected ray is the ray of light from the mirror to your eye.
All three must be in the same place, which is parallel to the plane of the table, on order for you to see the image.
Remember that 3 non-colinear points define a plane just as 2 points define line. Your eye, the point of incidence of the light rays with the mirror and the marker are three points in space. Therefore, they define a unique plane.

The second is owning a mirror. The reflective ray is you shouldn't of looked into it and the normal lie is, Is it really broken "YES"
