Hi. I'm Jimmy Chang and we're here to talk about how to cut an octagon through two opposite angles. Now, when you're cutting an octagon whether it there would be a regular octagon or not where all the angles are equal or not equal depending on how you drew it, the important thing is just make sure that to identify what angles are opposite and then make the cuts from there. So let's start out with a general sketch of an octagon. Okay. Now. In this particular case if you want to pick an angle arbitrarily , think about this angle and the angle that's opposite it is over here. So if you want to cut it like this, that's going to be one cut. And then, with this particular angle and them make that particular angle that's opposite it, you can make another cut. Now, if you think about this angle and there's another angle that's opposite that, you can make yet another cut. Again, just kind of a rough sketch so you might have some rough cuts as well. And then this particular angle and this particular angle that's opposite it, you can make another cut like that. So depending on how you draw it, the cuts might be done in a way that everything is going to be a lot neater but as long as you identify the opposite angles, you should be fine. So, I'm Jimmy Chang and that gives you a rough idea as to how to cut an octagon through opposite angles.
