If let's say it opened to here, it would be a 50 degree angle. Measured opened up this far, it would be a 10 degree angle. And then we're gonna measure the opening all the way to the other So that's nice, it'sĪlready lined up for us. So here's one of our rays, and it's lining up to The first thing we wanna do is make sure one of our Now the way we're gonna measure this angle is the same way we would Measure and angle of any size, instead of only anĪngle up to 180 degrees. A full circle is better because an angle can measure up to 360 degrees. Which is good, but aĬircle is even better. And those semicircle protractors measure from zero to 180 degrees. More semicircle shaped, something like this. What you're used to seeing, is protractors that are So here we have this blue angle that we want to measure in degrees, and it's sitting on top of this circle. But our angle measures all the way to here, to the 160 de ![]() And so if our angle only measured opened up this far, it would be a 10 degree angle. And then we're gonna measure the opening all the way to the other ray, to right here. So that's nice, it's already lined up for us. So here's one of our rays, and it's lining up to zero on the protractor. ![]() The first thing we wanna do is make sure one of our rays lines up to zero. Now the way we're gonna measure this angle is the same way we would on a semicircle protractor. So a full circle allows us to measure and angle of any size, instead of only an angle up to 180 degrees. ![]() Which is good, but a circle is even better. Sometimes we see, and maybe what you're used to seeing, is protractors that are more semicircle shaped, something like this. So here we have blue angle that we want to measure in degrees, and it's sitting on top of this circle.
