The Pilot’s Handbook of Aeronautical Knowledge addresses how dihedral effects lateral stability. The explanation talks about sideslip causing the low wing to have a higher angle of attack thus providing the force back to wings level. I think the explanation is incomplete or perhaps just wrong. Can someone offer a better explanation or perhaps elaborate on what the “sideslip” came from?

I thought dihedral geometry in a slight bank gives the low wing a greater vertical component of lift while the high wing has the smaller vertical component of lift and the stabilizing effect comes from that.
