i know that amino acids are 100% monomers, but monomers are identical units that join to make polymers, amino acids have variable R groups, but doesn't that change the function and structure of the amino acids that make it different to all the other amino acids thats join together?

They are called monomers because they will always be able to bind to each other to create a polymer (as the it occurs between amino and carboxyl group), regardless of whatever the R group will be.

i know that and i absolutely agree but doesn't the R group change the function of the amino acid so how can we say that the amino acid is a monomer of their are different r groups in the amino acids because they arent identical to each other anymore

Each monomer (or repeating unit) in a polymer sequence does not have to be the same

Well why would all the monomers need to be the same? All they need is to be able to link together.

R groups technically don't change the structure but the bonds that can be made with different r groups allow different structures, I.e, di sulphide bond. There are 20 types of AAs each with slight variation, monomers are just single units that combine together to form polymers, the bond formed between two AAs is called peptide

monomers are identical units, so of course they have to be the same
