The vertebral column articulates at the superior end with the skull, inferior portion with the pelvic girdle, & the ribs laterally.
An appendicular skeleton is composed of 126 bones of the appendages, and pectoral and pelvic girdles.
pelvic gridles
One side of the pubis articulates interiorly with the other side of the pubis, joining at the pubic symphysis. Posteriorly it articulates with the sacrum, the Acetabulum proximally articulates with Femur bone. So therefore there are three articulation points for the pelvic girdle.
ilium
no, they are found in the appendicular skeleton
The appendicular skeleton is what makes up the limbs as well as the shoulder and pelvic girdles.
The pelvic girdle and the thoracic girdle. You are familiar how a body girdle goes around the body. These are the same. They make a girdle around the chest and around the pelvis.

The illium, ischium, and pubic are the 3 pelvic bones that articulate with the pelvic girdle
The weight of an amphibian's body is transferred to the limbs by using the pectoral and pelvic girdles.
The Skeleton can be divided into Axial and Appendicular portions. The Axial Skeleton, is the head and trunk, and include the bones of the skull, hyoid bone, vertebral column, and thoracic cage. The Appendicular Skeleton, contains the pelvic and pectoral girdles, as well as the upper and lower limbs. The limbs and girdles, of the Appendicular Skeleton, attach to the Axial Skeleton.
