Hmm.  I think you could create a triangle using the "star" tool, and
stick a straight line to it.  Then make a group of both (Ctrl-G IIRC).
Then you can make duplicates (Ctrl-D) of the arrow and move/rotate
(Alt-mouse or Ctrl-mouse IIRC -- press the key and watch the statusbar)
them to wherever you need.

I also used inkscape some time ago and I found it very good.  It took me
a while to get used to it though (and I'm not claiming I'm an artist.)
