Let's Play Ancient Greek Geometry

I got a triangle made inside a circle. Can someone tell me why the triangle in origin circle thing doesn't complete?

It has to be in a circle of "origin" size, that is the radius of the circle must be the distance between the two starting dots.

Thanks, the phrase "origin circle" did not suggest that meaning to me at all. I thought maybe it meant that it had to be at the origin, but i couldn't figure out where that was.

I'm still stumped. Isn't this an 'origin circle' then? Radius == the pt-pt distance.

Scratch that - the same thing works if rotated:

It actually has to be one of the first circles you can draw (a point on the edge and a point on the radius). Not just the same radius.
