No, not really--although they are similar in overall layout, the F100 is a direct descendant of the F28, which Fokker developed independently more or less at the same time (early 60s) as Douglas was designing the DC-9.
It would be more accurate to say that both are clones of the pioneering Caravelle, which also has two rear-mounted engines and 5-abreast seating, but was flying years before either of the other two was on the drawing board.
where the a/c on the left is a F100 and the one on the right is a DC9-50. You'll notice the DC9 has 'eyebrow' windows in the cockpit, while the Fokker 100 has a longer nosewheel leg and bigger doors for the nose gear hold.
As ViveLeYHZ stated, the cabin windows are also different on those models, as the F100's windows are a bit larger and oval in shape, while the DC9's windows are more rectangular and smaller.
Tails are also different - the tailfin of a DC9 has a much smoother contour than that of a F100. Also note the tail cones - the Fokker jets have rear airbrakes, due to which the tail cone is not really a cone, and is much bigger than the tail cone of the DC9. Plus when it comes to larger models of the DC9 (DC9-50, MD80), you'll notice that the tail fins look very small compared to the rest of the fuselage.
But even though these two aircraft are slightly similar in looks, they were both designed in the same era, which means, as FoxBravo put it, not copies of each other but rather of the French-built Sud-Est Caravelle.
