# Showing the ratio of any two sides in a triangle is the same, given the shape of the triangle is invariant

Submitted by David Wees on Fri, 07/24/2009 - 18:34

If you drag point C, you can change the size of the triangle below dragging the entire triangle can be used to rotate it (around a point "near" B). Notice that the ratio of the three sides, shown on the right, does not change.

## your program doesn't work

your shizzle is broke

When i drag point C so that it's on A, your program says AB/AC=0/0 = .5

## I probably hard-coded the

I probably hard-coded the 0.5 into applet, hence it shows up for all values of AB and AC. Seriously though why does this correspond to "program doesn't work" since it only fails for exactly 1 value?
