In the course of almost any Instructables project, you will at some time have to find the center of some shape. However, this can sometimes be challenging. For example, the dimensions shape could be difficult to determine, or you might not have the tool required to do the measuring at all. Without the measurments of whichever shape you need to find the center of, it could be impossible to finish the Instructable. Now that would be very disappointing. This video will show you how to find the centers of many simple shapes without measuring, and the methods shown can be more accurate than measuring anyway.
I love the maple leaf rag. Good music choice.
How do you get the first line in the circle?
I think that you could draw just any chord.
i dont get the circle
The center that you found for the trapezoid is not the center of gravity, of course. I think this would be more useful.
