Consider a rectangular piece of paper ABCD, with AB = √2 and AD = 1. The rectangle is folded so that:
 B coincides with the point X on CD and:
 The resulting crease is AY which passes through the corner A.
Determine the length of the three sides of the triangle DXY.
Will publish path when I get more time:
DX=length 1
DY = length SQRT(52*SQRT(2))
XY = length SQRT(64*SQRT(2))
These match Charlie's sketchpad solution.
