What happens here

To use the speed square as a protractor, align the pivot point (the corner without numbers) at the desired point on the board. Rotate the square until the desired degree mark on the 'Degrees' scale aligns with the edge of the board. Draw a line along the straight edge of the square. Conversely, if you have an existing line, align the pivot point and one edge of the square with the existing line, then read the degree mark where the other edge intersects to determine the angle.

Goal: Accurately measure or mark angles in degrees.

part how we use the protractor look at the speed where if I make a mark boom I can tell you what that is just by going and my pivot point try it's 64 degrees yeah 64 degrees it where did you so let's do that again let's do that right over here I'm a fresh fresh spot so we can see this a little bit better Frankie so you're what you're saying is you can tell how many degrees yeah so I'm not even gonna I'm just gonna put the speed squared down draw it someplace and make a mark okay not even knowing what I'm making okay now if I wanted to figure what that out what that is you know I can come to the other side of the board go to the pivot point follow my line which I am it would be flirty I would say 49 49 degrees so Frankie's reading right here right now so this is 50 so he's reading this 49 degree mark so he's got his line here lined up and now he's trying to tell what this angle is but he's reading it over here as in degrees as in degrees and that's where that's the protractor okay that's just that's how the protractor works so any line that you want to try to tell you utilize this pivot point which is right here line it up on your line and most of your speech goes with tell you know that that's the pivot point I believe yeah okay so what are these no cool all new me see now these big sweet squares come with a couple of arms for doing steps it possibly four steps I don't know I've never I guess I've never used them I've never used that slot okay so now this next one is we're gonna convert from a 4-12 cut to a degree in a chop saw to
