An imperfect rhyme is when two words look like they rhyme but don't. For example cough and tough.
No, in order to be a rhyme, the end has to sound the same (although poetic license is often allowed for words whose endings are spelled the same but do not sound the same). But and cut rhyme. Pup and cup rhyme. Cut and cup do not.
makes things sound prettier
Yes, shirt and skirt does rhyme. For words to rhyme they don't necessarily have to be spelled the same, but if they sound the same that's fine!
Inside and outside do not rhyme. Rhyming occurs when words have similar sounds at the end of the word, typically the last syllable or sound. In this case, "inside" ends with the sound "ide" while "outside" ends with the sound "ide" as well, but the initial consonant sounds are different, making them not rhyme. Rhyme is based on the phonetic similarity of the ending sounds of words.
Technically no--for one of two reasons: 1) to "rhyme," two words must have the same "rhyme sound," preceded by a different "consonantal sound" and 2) the accent must be on the same syllable. (Note: the different preceding consonantal sound in the two words are "t" in "ten" and "c" in "-cent.") The rhyme sound in "ten" is "-en" and in "per-cent" is "-ent." "-en and "-ent" clearly are different rhyme sounds because of the "t" in "-ent." In pronouncing "percent," the accented syllable is arguably the second syllable "-cent" and thus that part of the definition of a rhyme is met, but the rhyme still fails because of the first part of the definition of a rhyme.

That question makes no sense. Please write your question in a complete sentence.
It's quite simply really, things sound better when they rhyme, like this; water lily, this is a badly written chime ;)
By modern standards, no. In the "rum ram ruf" alliteration sense (mostly) predating Chaucer, yes.
most of the poems make sense but not all poems rhyme
they sound the same but no they technically dont rhyme
No, they do not rhyme. "Grasp" has an "as-p" sound, while "blast" has an "as-t" sound.
No. It is a complete rhyme.
Rhyme, whether written or spoken, relies on sound; spelling is irrelevant in choosing rhyming words.
Technically, yes! It is called a sound-rhyme. The spelling doesn't rhyme, but the sound does. It is acceptable in poetry with rhyme scheme.
No, "for" and "yours" do not rhyme because they end with different sounds. "For" ends with the "or" sound, while "yours" ends with the "urs" sound.
No, "together" and "there" do not rhyme. "Together" ends with "er" sound, while "there" ends with "air" sound.
Yes, "beat" and "feet" rhyme because they both end in the "eet" sound.
