With ver 1.61 it produces:

With ver 1.63 it produces:

• @jfbu, the OP refers to the black bullet indicating the intersection. – Sigur Jan 26 '19 at 15:42
• The Section 3.6 from pst-eucl documentation shows the same problem. Looks like a bug? – Sigur Jan 26 '19 at 15:47
• One way it to pass none to each point: \pstTriangle[PointSymbolC=none,PointSymbolA=none,PointSymbolB=none](0,4){C}(0,0){A}(3,0){B} – Sigur Jan 26 '19 at 15:50
• Only the first point in the list of the three for the triangle has to be set additionally to none: PointSymbolA=none. And it makes no difference if your first point is named C – user2478 Jan 27 '19 at 7:01
• @Herbert yes, I loaded \pstInterCC normally.... – user173875 Jan 31 '19 at 11:11

Edit (based on @chishimotoji's comment)

Only PointSymbolA=none is enough to delete the black bullet.

But, that is strange to me since the bullet is at point C in coordinates (0,8) (note the change of units).

Pass the options PointSymbolA=none (and for other 2 points) to the \pstTriangle command.

\begin{pspicture}[showgrid](-5,-5)(10,10)

PointSymbolA=none,
PointSymbolB=none

• PointSymbolA=none, position " A " PointSymbolC=none, PointSymbolB=none are unnecessary... :-) – user173875 Jan 26 '19 at 15:56
• @chishimotoji, sorry. Could write it better? I wrote 3 lines of codes. Are you saying that only one is needed? – Sigur Jan 26 '19 at 16:01
• Oh no, I think there is a problem with the first position of \pstTriangle[Options](){A}... – user173875 Jan 26 '19 at 16:08
• @chishimotoji, I edited. – Sigur Jan 26 '19 at 16:09
