Another folded paper (Posted on 2012-01-03) Difficulty: 3 of 5
Start with a square of paper ABCD.

Fold corner A down to lie somewhere along side CD. Call x the portion of the way from C to D.

Corner B is outside of the original square and is now one side of a small triangle whose opposite side is along the remainder of side BC.

(A) Where would A be folded to make this small triangle isosceles?

(B) Find a formula in terms of x for the perimeter of this small triangle.

(C) Where would A be folded to maximize the area of this small triangle?
