Showing the ratio of any two sides in a triangle is the same, given the shape of the triangle is invariant
July 24, 2009
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?
