Now a square pyramid section if the conic was a ellipse, we should expect the pyramid section to be a rectangle, for the rectangle is the analog of the ellipse. Instead, what we get in a cut is a trapezoid, the analog of a oval.

In that evidence of (2) begs the question of what is the analog of the Cylinder, since the cylinder section is truly a ellipse, but the cone section is an oval. So the analog of the Cylinder is a Rectangular solid and if you section the solid, you get just longer rectangles. So that a rectangle is the analog of an ellipse. Now if you section the square pyramid you get a trapezoid, never a rectangle.

So that is probably the most effective argument that anyone preaching a ellipse is a conic, is a failed screwball of perception.

The cone and cylinder is analog to square pyramid and rectangular solid.

Only a magnanimous fiend would want you to believe that a conic and cylinder both yield a ellipse, when one figure is OBVIOUSLY different from the other. Creeps, want other people to be creeps like themselves.
