They are called delta and wye (or Y) networks, because of their shapes. They can also be arranged as pi (π) and T networks. It’s important to recognize that in terms of electrical behavior, the delta network is exactly the same as the pi network and the wye network is exactly the same as the T network; they are merely drawn differently.
