They are lines along which some continuous variable is measured.
A time line is a number line of years
They both use numbers.
well they are similar because they bth got yo mom in it
they are both in chronological order
Most of the time, yes.
We switch the time back to normal in November
The lines are "imaginary", because they don't really exist in nature. We created most of those lines, mathematically, and we use these lines to help us describe where we are. We draw those lines on the maps and globes to help us describe things. There's one of those "imaginary" lines that have some physical meaning; the equator.
In telling the time. For example hours on a clock face, months in a year. Counting in dozens. In some mathematically challenged societies for lengths (feet into inches).
Most of the time trapezoids are similar but in some cases they are not Depends on what you call "similar." In mathematics, "similar" triangles have the same angles, but differ in size. One might be a shrunken version of the other. In that case, they are usually not. The only requirement for a trapezoid is the four sides with either pair of sides being parallel. So, yes, a square is a trapezoid as well. Try this: Draw two parallel lines. Now draw two lines connecting them anywhere you want. The enclosed area is the trapezoid. Can you see how there are an infinite number of trapezoids you can make?

Time Lines was created in 2006.
Yes - very much so. The frequencies of each note are mathematically related, and sequences of notes that are interpreted as pleasant or melodious also follow a mathematical pattern. Key transpositions and chord progressions can be worked out mathematically as well. The lengths of notes and time signatures are mathematically derived.
