In the upper, left corner, there are 2 hydrogens.
1 is attached to a carbon, with what looks like a be a very skinny triangle, and the other by a similar shape, but with broken lines that solid.
I've looked around. From what I've seen, I think the solid triangle means it's a polar covalent bond, with the electrons more toward the hydrogen, which I don't think means sense since carbon is more electronegative than hydrogen. I thought this because of the fact that the triangle's base is @ the hydrogen.
So really, what do they mean? I've no idea for the broken line bond.
