Graphics, Figures & Tables ⇒ Circles in PSTricks

[Mini]

Hello, I have two questions:

1) Is there an easy way to draw a circle inscribed inside a triangle (I'm currently doing this by trial and error)

2) Is there an easy to way to draw a circle through three given points?

Thanks

have a look at package pst-eucl.

Hi,

Thanks for that. I'm having a play around now.

But I have a question about the PointName feature.

How would I use it to label specific points? What am I doing wrong for labelling the triangles? They're all labelled as 'A' even though that's not what I've put.

Thanks

looks a bit buggy, you should use PointNameC=A until it
will be recoded in the package
