Why does the last time when you turn a shape for rotational symmetry not count towards the number of times it has rotational symmetry?

It depends on what you mean by "the last time". Your last time may not be my idea of last time.
The turn that brings the object back to its starting position IS counted but only if the object has at least one other position of symmetry. This is to exclude objects that have symmetry of order 1. These are not regarded as being symmetrical because then every object would be symmetrical.

How many rotational symmetry does a Trapezoid have?
0,one full turn doesn't count as a rotational symmetry

How do you count the lines of symmetry?
Fold (or pretend to fold) an object in half in different ways, and if the edges and corners match exactly up to each other, that is a line of symmetry. If you want to count all the lines of symmetry, use the method above but tally the amount of lines of symmetry you count.
Do you count neutrons to find an atoms identity?
If by its identity you mean its atomic number, no. Neutrons only count towards the Atomic Mass Number, or AMU.
How much lines of symmetry do hexagons have?

What is the significant figure 3.0800?
To figure out how many significant figures there are in a number you must first know the rules. All numbers 1-9 are counted towards the number of significant figures. The only number you need to worry about is 0.-If there are 0's between digits (like 105), they are counted towards sig figs.-If, to the right of a decimal point, the number ends in a 0, or multiple 0's (4.660), they all count towards sig figs.-If, to the left of a decimal point, the number ends in 0 (4500), the 0 (or this case zeros) do not count towards sig figs.-If there is a lone 0 to the left of a decimal point (0.112), the 0 does not count towards sig figs.With the number 3.0800, you know that the 3 and the 8 both count towards significant figures. The 0 in between them counts as well. Then the two 0's at the end count towards sig figs. In all the number 3.0800 has 5 significant figures.
Is a diagonal line of a rectangle a line of symmetry?
No because diagonal lines do not count. Even though they might fit perfectly inside the rectangle, but those don't count. Only lines going horizontally or vertically count as lines of symmetry. :)
