No, "one leg up one leg down" is not an example of alliteration. Alliteration is the repetition of initial consonant sounds in neighboring words.
yes Answer I would say not. Alliteration refers to a series of words beginning with the same letter or sound. An example is Sally sells seashells, etc
moving chief is the one upone us loved one and sad and happy ones
put one leg in front and the other leg behind and slide down
Its massive boner is erected and is used as a leg
Hopping
You hop.
Blood flows down into each leg, and it also flows up out of each leg. There is no other way for this to work; all the tissues of each leg have to get oxygen and give off wastes.
They sleep with one leg up because when they go to sleep they shut down half their brain.
If it raised both of them it would fall down. True but birds also sleep on one leg at a time, they can put half their brain to sleep at a time and rest on the 'awake' leg.
You have parallelism and alliteration but alliteration would be the main one.
You can't. With one leg measure, all you know about the triangle is one side (the leg) and one angle (the right angle). That's not enough to pin down any of the other parts of that triangle. There are an infinite number of different right triangles that all have one leg with that same length, and hypotenuses with all different lengths.
One example of alliteration in "The Book Thief" is in the phrase "frighteningly frail." Alliteration is the repetition of the same initial consonant sound in neighboring words.
