Has anyone completed this quest? I've checked my work with Wolfram Alpha and I cannot find a combination of fragments to fit the second window. I've also tried making every possible size of glass by systematically iterating through each combination. I have made many pieces of glass, but none of them fit. I tutor primarily remedial pre-algebra students so I haven't done this type of math in a while. If you could point me in the direction of appropriate topics to review, that would be greatly appreciated.Thanks!

I figured out what my misstate was. I missed a vital instruction - and maybe I should have known this, but I can guarantee my students will not pick up on this either. That instruction was to add the fragments to the triangle template in the correct order. To figure this out, I had to delete the quest and start over. In my trial iterations I never considered that 1, 2, 3 was not the same triangle as 3, 2, 1. I'm sure I learned this when I took tenth grade geometry over 20 years ago...

My students and I have been trying to use this tool for a few weeks now... still much more frustration/disappointment than learning...
