• I have a question. The dial above doesn't even go around all the way with all the settings.It just ends at high. So how can Lindsay say that the middle is 180 degrees? I mean, I know a straight angle is 180 degrees but if it doesn't go all the way. . . isn't it like those comparing number lines where if the number lines itself aren't the same length as the other number line it would be hard to judge or maybe even not-able-to-be-solved? Thanks. Please answer.

• isn't a 180 dergree angle just a line, not 2 rays?
