In the human projection, we can visualize this back carbon blue atom that's given here, as well as this first carbon atom. Green one here, given by this intersection. So the angle between any two bonds here is 60 degrees, as we said earlier for the staggered. So the angle here between any two ch bonds is zero. The angle here is 60 degrees. And the angle between any two of these bonds, for example, this green ch bond.
