They refer to the time - in hours. The slanted edge of the gnomon casts a shadow on the sundial at the position which represents the time.
Because they want to and it's a free country.
The only specialized word I can think of for the difference between two squares is "gnomon", and it's called that because it sort of looks like one (a gnomon is the word for the "pointer" part of a sundial).

gnomon
It doesn't. The gnomon is supposed to match the latitude of the location where the sundial is placed. If the latitude is 30 degrees and the gnomon is 45 the entire sundial will have to be tilted to keep correct time. Another way to describe this is to say that the gnomon should be parallel to the Earth's axis.
Gnomon
A gnomon is the upright piece of a sundial, and it is the part that casts its shadow down onto the dial to indicate local solar time.
The `Gnomon` is the part of the shadow clock, or sun dial, that casts a shadow onto the face from the sun, so that the time can be read.
The stationery arm of a sundial is called the "gnomon." It is the part that casts a shadow onto the dial face to indicate the time.
The pin of a sundial is called a gnomon. It is the part of the sundial that casts a shadow onto the dial face to indicate the time.
the shadow of the sundial is just called a shadow
The projecting piece of a sundial that shows the time by its shadow is called a gnomon. It is usually a thin rod or triangular blade that extends from the dial plate. The position of the gnomon's shadow on the dial indicates the time.
The pin of a sundial where the shadow falls is called the gnomon. It is typically a thin, straight rod that extends vertically from the sundial's base. The shadow cast by the gnomon is used to indicate the time of day on the sundial's face.
The projecting piece of the sundial that shows the time by its shadow is called a gnomon. It is typically a thin rod or plate that extends from the dial's face and casts a shadow onto the dial's surface to indicate the time.
invented by a greek person named anaximander..... he taught the greek philosopher who came up with the pythagorean theorem, which explains why the gnomon deals with trigonometry and also why there is also an unknown angle within the triangle that deals with the shadow created by the sun over the pole (gnomon).
