SUMMARY
The intersection of the plane defined by the equation x + y + z = 1 and the cylinder described by x² + y² = 1 results in an elliptical shape. The discussion highlights that when visualizing the intersection, one must consider the boundaries of the cylinder and the plane's orientation. The user mentions drawing the intersections at z=0, y=0, and x=0, which leads to a triangular shape, but the correct interpretation reveals that the intersection is indeed an ellipse, as the plane slices through the cylindrical block.
