Main Question or Discussion Point

I understand that this will be a simple question, but I am having a difficult time understanding what is going on in the situation when two rods are pinned together.

The situation is this: imagine that you have three rods arranged to form an equilateral triangle and each of them are pinned together at the connections.

My question is: do the pins exert reaction forces on each of the rods that can be split up into horizontal and vertical components? If so, for two rods that are pinned together, will the individual components of the reaction forces be in opposite directions?

Thanks in advance.

Think about making a FBD for the pins themselves.
