# If 2 identically-sized rectangles overlap with another rectangle and are evenly divided by an axis, which overlap rectangle would be biggest?

Suppose we have three rectangles, named 1, 2, and 3. 1 and 2 are identically sized, are axis-aligned, and overlap with 3, but not each other. 1's center is closer to 3's center than is 2's center. Is it safe to say, then, that the rectangle created by the overlap of 1 and 3 is bigger than the rectangle created by the overlap of 2 and 3? My intuition says "yes".

• @Element118 Yes. – moonman239 Dec 12 '15 at 3:38

Suppose rectangle 3 is a square of side 2, centered at the origin, rectangle 1 is centered at $(0,1.1)$ and has height just over $1.1$, rectangle 2 is centered at $(.9,-.9)$. I think you'll find your hypotheses are satisfied, but not your conclusion.
