Rhyming words

When I think of poems I expected them to all rhyme which means the last word of every line except for one or two had to rhyme. It wasn't until first grade when I first saw a not rhyming poem but what is the definition of it anyway do you know? Then out of all the poems only one rhymed but not all the lines they were in a pattern which I later learned in third grade a few weeks ago I learned that rhyming poems have a pattern to rhyme in each line is labeled A B C sometimes but rarely you use D E. You use a letter twice if two lines rhyme the most popular patterns are A B A C, A B C B, A A B C, A B C C,or A A B B. An example is I ran to the park I fell on the sidewalk I tripped over slush so then I took some chalk. Which is A B C B. I used to love writing a simple poem like this A A A A A A B A A A C. If it went on it would probably hit X and Y's. I like poems.
