The hip is simple in it's joint configuration, but very complex in its function. Like the shoulder, it is a ball and socket joint. That means that the thigh bone has a spherical head (femoral head) that fits into a cup-like socket (acetabulum) of the pelvis. This type of joint offers high freedom of motion to allow us to get down into a squat, high kick, dance, karate, etc. Compared to the shoulder, the hip has a little less motion in order to provide stability, and the femoral head can sit deeper in the socket of the acetabulum in order to prevent dislocation.
