Two lines of symmetry; one vertical and one horizontal
2 Four if the cross bar is in the middle-- two diagonals, vertical and horizontal axes.

It depends on the rotation of the square. If it is aligned to the X and Y axes, then there are two horizontal lines. If it is not aligned to the X and Y axes, there are no horizontal lines.
Three * * * * * Just one - horizontal. Don't know where the other two are meant to be.
A capital "B" has one horizontal line of symmetry.
There are 2 horizontal parallel lines in the letter Z

Four. * * * * * I would say just 2: horizontal and vertical.
I think 8.
The capital letter L has zero. It's not symmetrical no matter how you slice it. The lowercase letter l has two, one horizontal and one vertical.
It depends on the rotation of the square. If it is aligned to the X and Y axes, then there are two horizontal lines. If it is not aligned to the X and Y axes, there are no horizontal lines.
The number of horizontal lines depends on the resolution of the picture. The 720p is a progressive HDTV signal format with 720 horizontal lines. Many systems have more than that number.
