The Golden Triangle & Design?

I was doing some work for a graphic design firm, and I heard a conversation about using the golden triangle in design. I think it has to do with proportion, but I’m not sure. I tried googling and didn’t get much.

Anyone know what the golden triangle is or how to use it?

Thanks.

Its related to the Golden Ratio, if you scroll down this article its in there.


“The golden triangle can be characterised as an isosceles triangle ABC with the property that bisecting the angle C produces a new triangle CXB which is a similar triangle to the original.”
