Rotation of the hip
Hello
I am doing a fitness trainer course alongside my computing and I am confused about the terms used to rotate the hip. The images on Google images also seem to be conflicting
Imagine the knee is bent and lifted up I thought lateral rotation was moving the hip away from the midline of the body to the leg makes a 'r' shape with the feumr being the top of the r and medially rotation was turning it back to its starting position.
This page states that external rotation is lateral rotation and it is the rotary movement that is occurring in the vertical axis when the femur moves away from midline, thereby turning the thigh or pelvis outward.1 the hip can rotate externally 45 degrees.

I extrpaolate from that that medial roation is internal rotation. Correct?
However the image I have attached called incorrect internal and external extension seems to suggest the opposite of the website. The second image is what I would have expected to see
Is the first image incorrect or have I misunderstood as there are so many different sites and pictures it can get confusing. But the second image is intuitive which does make it feel correct. The first image could be a labeling error. I hope so :)
Many thanks in advance

The confusing part:
Image 1 - diagrams the rotation direction of the foot
- if the foot moves 40 degrees outward, the hip would make an internal rotation
Image 2 - diagrams the rotation direction of the knee
