mirrior line is when you see two line means double line.
mirror line
Reflective symmetry is when you have a shape (a letter for example, even though they are weird shapes) and you can put a line through it called a mirror line. On the mirror line you put a mirror on it and you can see a half of the shape reflected to make the complete shape.You must be able to do this on both sides of the shape otherwise it won't have reflective symmetry.Take the letter E for example. If you put a line straight through the middle of it horizontally it would be a mirror line.
The LINE of symmetry
Assuming you're talking about transforming graphs, you mirror the graph along the line y = -x.
Think of the line of symmetry as a mirror (indeed try using a small hand rectangular hand mirror). a symmetry either side of a line is like a reflection of one side in the mirror.
Line of symmetry
line of symmetry is divides a figure into halves are the mirror images ofeach other
mirror line
It refers to the reflection of an object across some line.
Reflective symmetry is when you have a shape (a letter for example, even though they are weird shapes) and you can put a line through it called a mirror line.

The distance of the object from the mirror line should equal the distance of the image from the mirror line.
If it is a circular mirror the line would be called a radius. If it is a rectangular or square mirror it would just be called a diagonal or straight line... nothing special
The LINE of symmetry
the line of reflection
90 degrees (That line is the normal to the mirror.)
A line of symmetry is a 'mirror image' of a shape.
The normal (ray).
