Okay, let's try a visual representation.
A zigzag pattern: /\/\/\/\/\/\
A zigzag step: /\
If you notice that this is a full step of those which make up the pattern.
But here's another zigzag pattern:
/\
/\/\
/\/\/\
/\/\/\/\
Of which /\ is a full step. Representing a nexus point of divergence.
Please try and comprehend that a zigzag is a turn or angle, just as a turn or angle can be a zigzag. Though zigzag has often been used to describe a continuing pattern of zigzagging, that is not its absolute definition.
In the South, they refer to a pattern which continued one angle past a simple zigzag step as a 'dog leg'. Interesting how they also incorporated two three-letter words which ended in 'g'. :-)
