No, it does not. Take a sheet of A4 paper and fold it across the diagonal, and you will see that the two halfs do not line up.
A diagonal is a line so the area of any diagonal must be zero.

No, line symmetry and diagonal symmetry are not the same. Line symmetry, also known as reflection symmetry, occurs when a figure can be divided into two equal halves that are mirror images of each other across a line. Diagonal symmetry, on the other hand, occurs when a figure can be divided into two equal halves that are mirror images of each other across a diagonal line. In essence, while both involve symmetry across a line, the orientation and positioning of that line differ between the two types of symmetry.
If you had a circle and you halved it, exactly in the middle, then that line would be a line of symmetry! And it is the same with a square. If you halve it exactly in the middle then that would be called a line of symmetry! And then all the lines of symmetry in a square are down, across, diagonal from the left and then diagonal from the right! But in a circle there are LOTS of lines of symmetry!

That is the bias. When you have a pattern that states "cut on bias" the pattern piece would be placed in a fastion that would be a "diagonal line against fabric grain". Pattern pieces cut in this fashion are sometimes more difficult to sew because when fabric is cut on the bias it gives the cut edge more of a stretch.
an oblique or diagonal line of direction, esp. across a woven fabric.
a line going diagonally across the grain of fabric
Straight line ending in arrowheads, means "place on straight grain of fabric."
No, it does not. Take a sheet of A4 paper and fold it across the diagonal, and you will see that the two halfs do not line up.
To achieve a clean and precise diagonal cut when working with fabric, use sharp fabric scissors and a ruler to guide your cut. Make sure the fabric is flat and smooth before cutting, and take your time to ensure a straight and accurate cut along the diagonal line.
Three vertical lines, |, with a diagonal line across them.
The way the fabric is woven gives it different properties in different directions. When you are cutting a pattern you want to get all the pieces on the same "grain", i.e. a piece that will be vertical on your body should not be cut diagonally on the peace of fabric (unless you cut all the pieces diagonally or on the bias). The grain of the fabric is the natural direction of the fabric. The selvage is the edge of the fabric. When you buy a piece of fabric from the roll, you get two cut edges that fray and two factory edges that look different from the rest of the fabric and don't fray. These edges are the selvage. If the grain of the fabric runs from selvage to selvage that means the natural direction of the fabric (that you should use to line up your pattern pieces) runs straight across the fabric from factory edge to factory edge.
