The only difference is they all lie in different directions. So they point in different directions. So that means because we're combining two P orbitals and one two S orbital, we're going to have 66% P character and 33% S character. So now that we formed the three different hybrid orbitals, we are ready for these orbitals to interact with the one S orbitals of the H.
So we take three one S orbitals, we combine them with three SP two orbitals, and we form the following picture. So here we have our boron atom. The nucleus is in the middle here.
