Care to post an image with that question? It will really depend on the image content.
For example if it is something like this

you could use the RGB filter and then the blob filter to look for a "triangular blob" to result in
See attached robofile.

And then for the direction use the Geometric module and see the angle variable. Note that this only works for an asymmetric triangle as a symmetrical one has no intrinsic angle.

mehdi,
You can try looking in open source solutions for source code. See the list we maintain at
http://www.roborealm.com/links/vision_software.php
that have a lot of source code available for investigation. We're not sure exactly which package would have an orientation algorithm but I'd probably start with ImageJ.
