Unless you can back up your answer, there is a 75% chance you are just going to mess up someone's homework.

@ellamoyseyuk , _sketch_ the four _regular_ polygons listed, including the apothem; and then see if you can find a special triangle connected to them.
Here's an example for the octagon, although that is not on your list.
