Good point. If we define an ellipse by the locus of points whose sum-of-distances to two given points is a fixed constant, what is the shortest proof that these two segments make equal angles with the tangent line? (Assuming the ellipse surrounds a positive area.) —Dan

Let's focus on the important points here. The elliptical table is what's interesting. I'm sure Alex is eccentric and this is reflected by his choice of adjectives, but let us put away the axes because we all know he's affine fellow.
