Take radish as an example. What is crosscutting in mathematical language? What is vertical cutting? What is lateral cutting? It's urgent ! ! ! !
Cross-cutting: place the radish horizontally so that the cutting plane is perpendicular to the central axis of the radish. Vertical cutting: keep the central axis of radish vertical, and make the cutting plane horizontal with the central axis. Side cutting: the cutting method of placing the radish horizontally with the central axis so that the cutting plane is horizontal with the central axis. My language level is insufficient, which can only be described as this. If you think it's okay, please adopt it.
