Never give up. You will never fail, but you may find a lot of ways that don't work.
if you have 'show rotation handles' button pressed on the infobar you will see rotation origin point on both, easy done

It's interesting to see how Xara determines the centre of a triangle & and it's centre of rotation.

we had a thread about this a while back - the geometricians [is that a word?] were musing on the ways of defining theoretical centres of asymmetric objects...

Well it is now. I remember that thread... geometricians [is that a word?]

I haven't time to check it out - but is the xara way you posted based on the four quartiles of the triangle all having the same area in terms of square inches/cm/pixels [square pixels, there's a concept...]
I once asked a xerox machine operator to reduce an A3 sheet down to '50% fixed aspect' [ie A5] - back came an A4 sheet.. well you asked for half size was the explanation which it is by surface area, but it was not what I had actually asked for.... I actually asked for a 50% reduction to both axis...

I'd just ask for an A5 next time
Xara determines the centre of rotation to be half the shapes bounding box's x & y value. This can be odd if a triangle is rotated.
The centroid indicated on a triangular quick shape however is determined by the intersection of lines from each corner to the half way point of the opposite edge.

you are right of corse - I was just forgetting 50% is a special case [in terms of A sizes] as opposed to say 32%.... someone took what they thought was a 'short-cut'
the rotation point can be moved of course....
