Graphical Construction – Bisecting an Angle

Bisecting an Angle.

Bisecting an Angle.

In the last post I bisected a line, so in this post we will bisect an angle. Again this is trivial in CAD, but a little more complicated in”real life”. Basically all that is being done is to: First, make the two legs of the angle the same length and then form a perpendicular bisector to the line between the two new end points of the angle. The video this time shows the CAD easy version, the complicated semi-manual CAD version, and the completely manual pencil and paper version.

The e-mail “smoke test” was a semi-success. I did not reach the limit imposed by my hosting provider. However it is only a temporary fix because it took forever, and I must leave the browser window open for it to complete. Like always I have another work-around planned…. like always it takes time. So repeat after me: “Cuss Cuss… Fuss Fuss.”

In a most excellent book I read a long time ago, Zen and the Art of Motorcycle Maintenance, An Inquiry Into Values by Robert M. Pirsig, the term “Gumption Traps” was used.  These are things that suck the life out of you preventing you from accomplishing tasks.   A major gumption trap to me is having a big “wanta to do list” and the tools I have on hand are broken or can’t do the job.  This e-mail situation is just one of those sorts of things.  I WILL PREVAIL! 

Anyhow… enough ranting.

I received an e-mail today from a subscriber to this blog, Frank Moore. He gave me a link to a very interesting math site,  Euclid’s Elements.  I have not had a chance to look at it much yet, but it looks like some good stuff…. very good stuff.  Thanks Frank.

The video showing how to bisect the angle is embedded below.


No mention of subscribing tonight…. I have to get what I got working right first!
