[pstricks] Points of Intersection

[David Arnold]

All,

Suppose that I want a triangle having sides measuring 4, 5, and 6  
units. Using Geometer's Sketchpad, or Geogebra, I could draw a  
segment AB of length 6, then add circles of radius 4 and 5 with  
centers at A and B, respectively. I then could choose on of the  
points of intersection of the two circles, call it C, and I would  
have the needed triangle ABC.

Now, in pstricks I could do some trig, come up with some angles, and  
use a polar coordinate representation of the point C.

What I am wondering is this: Is there a slicker way of accomplishing  
this goal of drawing a triangle with sides 4, 5, and 6 units?

Suggestions are most welcome.

Thanks.

D.
