Four Equal Triangles (
Posted on 20130616
)
Here's a problem I found in the Problems section of a
math journal. The way I read it, it is not true.
Let ABCD be a convex quadrilateral. Prove that
there exists a point P inside ABCD such that
[PAB]=[PBC]=[PCD]=[PDA],
if and only if
the diagonals bisect each other.
Here [XYZ] denotes the area of triangle XYZ.

I arrived at the same conclusion.
What about restating the problem by replacing
"the diagonals bisect each other"
with
"at least one diagonal bisects the other"?
