You can use either of the lines. The top one is better for high resulution moniters, and the bottom for low resulution. What you do is you look at the "X" with one eye open, and move your face closer and further away from the screen. At one point, the flower dissapears. This is because there are no rods and cones in one spot on your eye.

as to the above problem, the "hypotenuse" of the "triangle" is not a straight line, the small triangle has an aspect ratio of .4 and the large has a ratio of .375. the space for the "missing" square is encapsualted in the area created by the slight bow in the upper left face of the bottom shape

the two shapes are just slightly different.
