A real Treasure Trove! :) From total beginner to more advanced.

Wow! Simon Gregg got playing with the same 20-80-80 triangle as I did, but his results are a lot prettier! Read the post. Wonder at the marvels.

Two curves cut all circles at right angles: straight line and a tractrix.

I didn’t know what a tractrix was, so I Googled it! Tractrix definition from Wikipedia: Tractrix (from the Latin verb trahere ”pull, drag”; plural: tractrices) is the curve along which an object moves, under the influence of friction, when pulled on a horizontal plane by a line segment attached to a tractor (pulling) point that moves at a right angle to the initial line between the object and the puller at an infinitesimal speed. 
Here’s a gif from Wikipedia showing a tractrix being created from dragging a pole:

Heptagonal Hyperbolic. John blogs at Azimuth, might want to check it out. Lots of mathematical study of climate change.
