The ray diagram was confusing on this video. The P ray seemed to show that the focal length was half the thickness of the lens. Also, the "small" triangle (on the image side of the lens) didn't have the horizontal leg going to the center of the lens like the "large" triangle did. I would have thought the horizontal legs of each triangle would go to the middle of the lens.
