Superfícies regradas não-desenvolvíveis é o nome dado às superfícies em que não é possível planificar, ou seja, não é possível pegar uma folha de papel e desenhar todas as partes para depois serem uni

Considering the properties of non-developable ruled surfaces, analyze the following statements: I. Two lines of the surface infinitely close to each other do not intersect. II. Two lines of the surface infinitely close to each other intersect. III. They can be represented on a plane. IV. The tangent plane to the surface at a point contains a line of that surface that passes through that point, but is not tangent to the surface at other points of that line. Choose the alternative that presents the correct sequence:

I. Two lines of the surface infinitely close to each other do not intersect.
II. Two lines of the surface infinitely close to each other intersect.
III. They can be represented on a plane.
IV. The tangent plane to the surface at a point contains a line of that surface that passes through that point, but is not tangent to the surface at other points of that line.
