Inscribe a Circle in a Square

Circle, Square
In the given Square, construct a circle which is inscribed. Inscribed means that the circle touches the edges of the square at exactly one place on each side; see the image below. Your construction should pass the "drag test" which means if I move your blue points around, your picture should stay correct! If you get stuck, use the video to help you along but try to do these on your own! There are multiple ways to construct the circle!
