What does "coterminal" mean?

Anhy didn't respond to my question, so I'll just go ahead.
Coterminal means "having the same initial and terminal sides". That is, they look the same, even though they may involve more revolutions.
In this case, we need to find an equivalent positive angle for `-205^"o"`. This means the angle goes in a ,strong>clockwise direction (since the angle is negative), just a little more than a straight angle (`180^"o"`).
It will be `360^"o" - 205^"o" = 155^"o"`
So the required positive angle is `155^"o"`.
