I am in Chem 2 and I dont know what I am not understanding about polarity and bond angles of molecules so I would like some answers lol. Like what makes molecules polar or nor polar in specific. Thanks in advance!

Specifically I start to think of it in terms of symmetry. Water is polar, methane (CH4) is not. On the Y axis, each half of a water molecule is half an oxygen atom, and one hydrogen atom. It’s symmetric. On the X axis, you have an oxygen atom, or two hydrogen atoms. Not symmetric. Therefore, it’s a polar molecule. Methane is always symmetrical, so non-polar. After that we start driving into electronegativity… But that’s a bit deeper and I’m on a phone.
