Phylum.
Both classes are modal classes.
they are grouped by the number of valence electrons.
They are both modal classes - the distribution is bi-modal.
Group are based on similar properties. The elements having same chemical properties are grouped together.
A group of individuals ranked together as possessing common characteristics; as, the different classes of society; the educated class; the lower classes., A number of students in a school or college, of the same standing, or pursuing the same studies., A comprehensive division of animate or inanimate objects, grouped together on account of their common characteristics, in any classification in natural science, and subdivided into orders, families, tribes, genera, etc., A set; a kind or description, species or variety., One of the sections into which a church or congregation is divided, and which is under the supervision of a class leader., To arrange in classes; to classify or refer to some class; as, to class words or passages., To divide into classes, as students; to form into, or place in, a class or classes., To grouped or classed.

Elements in each group on the periodic table have similar properties due to their similar electron configurations. These properties include similar reactivity, chemical behavior, and physical characteristics. This allows for elements within the same group to be grouped together based on their shared properties and patterns.
The phylum that contains the classes Trematoda, Cestoda, and Turbellaria is Platyhelminthes. These classes are all part of the same phylum due to their similar characteristics, such as being flatworms with bilateral symmetry and simple body structures.
In the Linnaeus system, organisms within the same class contain similar phyla. Classes are one taxonomic rank above phyla and encompass groups of organisms that share similar characteristics and evolutionary relationships.
Well, considering all life on earth originated from a common ancestor... and both humans and cows are mammals... one can assume we have similar traits.. since we are both grouped in the same class.
they are grouped in the same family because they react, behave, and act in the same way.
Animals or plants that are grouped together in the same class - usually exhibit common traits. This helps to classify new discoveries so they're grouped with similar organisms.
