How to align objects with different sides?

[Rookie Chicken]

In case I want to align from right side of object A to left side of object B, or if I want to align from top side of object B to bottom side of object B
Is there any convenient method?

Can I align objects' anchor points or lines?

With Smart Guides on, you should see the guides when you simply drag one shape close to the other. Does that work for you?
