Triangle Point Translation

I know this should be easy, but it's been a long time since I took geometery and I can't seem to get this right.
I have a triangle, defined by three points (x,y).
It does not have to be equilateral or symetrical, but all interior angles are acute.
I'm trying to find an equation to shrink/enlarge this triangle by a specific amount (width/height) and have all three points move away from the center to make the triangle fit this new space.
I tried using an equation on each point to find the slope and then move that point a given amount along that trajectory, but I can't even seem to get that to work right ;)
If anyone out there can help me with this, I would very much appreciate it. Math never was my best subject in school ;)
