In this video, I'll demonstrate how you can inscribe and circumscribe a square. Let's begin by drawing a horizontal line. And then place a circle on that line. Let's label the points A, B and C. And then put in a perpendicular at B. I'll label these points D, and E. So already with a 90 degree angle, I have enough to create a square. I can just draw that in. But what if you wanted the square to be rotated 45 degrees with respect to the original line?

Well, I'll just go back a few steps. To do that can bisect the angle dBc. And the angle below angle CBE? We can just connect these dots We have a square rotated. Now what if we wanted a square that was circumscribed about the original circle? Let me just go back to this point, and I'm going to change the color of the original circle to black for clarity.

I'll draw a new circle from A to B, and another one from C to B, and then D to B and E to B. So we have four circles surrounding the original circle. Then drawn your square
