Level 25 solution not accepted #305

Open s5b opened 10 years ago

s5b commented 10 years ago

This game is great. It's just the sort of challenge I like. I have been stuck on Level 25 for more than a week. In desperation, I started looking for geometry lessons on the internet to increase my skills. I came across this method https://www.youtube.com/watch?v=tbPCFoj8Duw which when applied appears to solve the level, but is not recognised by the application. Is the method wrong, or is the application just not recognising it as a solution?

I haven't looked at the comments on the Level 25 page for fear of seeing spoilers. :)

I have now found this method https://www.youtube.com/watch?v=LBgIWQcC6lM, which gives an acceptable (correct) answer. When I superimpose the method linked in my original post then I see that that method doesn't appear to give the correct answer. Thus, it seems that the application is correct and that the referenced method in the original issue is wrong. Closed.

I actually managed with your initial strategy by devising a method for finding the five equal parts of the diameter. After 22 moves, I got a completed pentagon, but since it's sideways (and I didn't plan ahead) the software doesn't accept. Though I imagine it would. Thanks for that, though. I now have a cool way to get 5-way splits on segments, based partially on a previously-found method for trisections.
