Minimizing Length of a Crease
I have been working on this problem for a while now, i have nailed the other 2 cases possible for this problem but the last case has me stuck
here is the problem
You have a sheet of paper that is 6 units wide and 25 units long placed
so that the short side is facing you. Fold the lower right hand corner
over to touch the left side. Your task is to fold the paper in such a way
that the length of the crease is minimized. What is the length of the
Do with without using trigonometry
currently i am working on the case on the far right (i have completed the first two)
This is the diagram that i have made.
Everything that is not in computer font was what i originally had drawn myself. The computer additions are what my teacher added to my diagram, all of which have confused me even more.
My professor has told me that i have to relate L (length of the crease) in terms of x. He has also given me A which he says i will needed. I dont know how these variables relate or how to start this problem
If any more diagrams are needed i will provide them on request
This is urgent i need to turn this in asap
Thanks for taking your time to look and help me
Re: Minimizing Length of a Crease
Only in case it isn't quite clear which geometric properties I used I've attached a more detailed sketch.
Prove that the angles marked in orange are equal. Show that the grey triangle is isesceles because the base angles at the red base are equal.
