Equilateral Triangles

[Kay C Lan]

What I should have said:

If you already have the triangle images, and they have no margin, so a 200
pixel triangle should be a rectangular image 174 pixel tall and 200 pixels
wide, then adding a 7.5% margin to the left AND right of the image (15 %
total) and a 32% margin to the bottom, should result in a square image with
the triangle centre in the centre of the image.

GraphicConverter can apply such margins to a batch of images quicly and
easily
