Lay eggs.
The most common reproductive strategy in all groups of reptiles is that of laying eggs.
Edit: The 'reproductive strategy common in all groups of reptiles' is - internal fertilization through copulation. This distinguishes them from amphibians who lay soft-bodied eggs in water, which are then fertilized by the male ejecting a 'cloud of sperm'.

flying reptiles are in fact birds. as animals are now being classified into monophyletic groups, we must include birds as reptiles as well because they came from a common ancester
Vertebrates are classified into five main groups: mammals, birds, reptiles, amphibians, and fish. They are grouped based on common characteristics such as skeletal structure, reproductive methods, and habitat preferences. Each group further consists of various species with unique characteristics and adaptations.

The reproductive systems of frogs, milkfish, lizards, turtles, and chickens all share certain structures, particularly in the male reproductive system. For instance, both frogs and reptiles (like lizards and turtles) possess testes and cloacas, which serve multiple purposes in excretion and reproduction. In females, the presence of ovaries and oviducts is common across these species, facilitating egg development and transport. However, the complexity and specific functions can vary significantly among these groups due to their different reproductive strategies.
The largest group of reptiles are birds, lizards, snakes, and turtles.

Reptiles, fish, and amphibians
They are all vertebrates, and the reptiles and amphibians belong to the tetrapods because they have four legs.
