MAVERICK [17]

1.) A straight line section can be drawn joining any two focuses. 
2.) Any straight line portion can be expanded uncertainly in a straight line. 
3.) Given any straight line fragment, a circle can be drawn having the portion as a span and one endpoint as the inside. 
4.) All correct points are harmonious. 
5.) If two lines are drawn which meet a third such that the total of the internal points on one side is under two right edges (or 180 degrees), then the two lines unavoidably should converge each other on that side if reached out sufficiently far.
