On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Anode and cathode. Anode = negative lead, cathode = positive lead.
A positive times a positive equals a positive, a negative times a negative equals a positive, a negative times a positive equals a negative(vice versa for the last one)
If your point is positive positive it is in 1. If tour point is negative positive it is in 2. If your point it negative negative it is in 3. And if your point it positive negative it is in 4.
The answer will depend on the context in which the legs are defined. Since no information on that is provided, it is not possible to give a more helpful answer.
The longest leg is the positive leg of any LED.
the negative leg is shorter than the positive leg.

I'm not sure what you are asking. Could you please provide more context or clarify your question?
The longer leg of an LED is typically the positive (+) terminal, while the shorter leg is the negative (-) terminal. Additionally, the positive leg usually has a flat edge or a notch near it as a visual indicator.
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Current flows from the anode (positive terminal) to the cathode (negative terminal) in a LED. The longer leg of the LED indicates the positive anode side, while the shorter leg represents the negative cathode side.
The longer leg on a LED light is called the anode. It is usually the positive terminal and is marked with a longer leg or a "+" symbol.
