About This Lesson
The 61st in Mr Barton's Autograph Video tutorial series. I was surprised that one of my 12th Grade students wasn’t aware of the fact that you can draw a circle through any 3 points, so long as those 3 points do not lie on a straight line. After an example with compasses and a ruler failed to convince him, I turned to Autograph, and this is the result! Clicking on the web-link you can see all the videos in this series.
