Reaching into the bag of diminishing memory, these codons, when read by the polymerase enzyme, triggers (Starts) the enzyme to begin the process of transcribing bases into RNA, then on to amino acids and finally protiens.

They are termed as such because they are part of the few codons which initiate the process of translation (where DNA becomes proteins)
The AUG you are referring to is ATG, which codes for Methionine, and is the most prevalent start codon for Eukaryotes and especially so in human beings.
Why is AUG (Methionine) termed the designated start codon for prokaryotes? Well, that's because the ribosome scans along the mRNA to find the first AUG sequence, and because most of the proteins in the body are made with Met as the first amino acid, it naturally should find the first AUG and start translation from there on. It is a fact that is acknowledged throughout the Science community and elsewhere.
And WHY is AUG the first amino acid for the proteins in the body? Who knows. Ask God, for he made the proteins that way.
lol.

When ribosomes encounter these codons, they begin translating the sequence at that point, and everything "downstream" of there gets translated until they get to the stop codons.

They're reminding you to START doing your own homework.
