Could someone describe the shape and bond angles of N2H4?

N2H4 is essentially composed of two trigonal pyramidal geometries. For example, if you look at one nitrogen, it is connected to 2 hydrogens and 1 nitrogen, plus a lone pair. You know this as trigonal pyramidal. If you look at the other nitrogen, it, too, is connected to 2 H and 1N, plus a lone pair. This trigonal pyramidal shape has a bond angle less than 109.5 because of the repulsions due to the lone pair on the nitrogens.
