Well im doing a project about ammonia and i cant find any where on how 3 ammonia(NH3) atoms would connect together. Would they be polar? or connected at the equator?

No, it is triangular pyramid.
Remember, N is in the second period and 5A group. Thus, its valence shell can hold up to 8 electrons, but itself has 5 electrons. When it bonds to 3 H atoms, N would have a total 8 electrons to satisfy the octet rule. These electrons would occupy 4 hybridized molecular orbitals called sp3 hybridization, originated from 4 atomic orbitals (1s and 3p), forming 4 electron pairs. Among them one is the lone-pair without bonding to anything, and 3 are the bonding electrons between the central N and 3 H atoms. Thus, NH3 is a polar molecule and it can hydrogen bonds to water molecule. That is why the solubility of NH3 in water is very high.
