copying, moving and rotating triangles

Hello everyone,

For a school project I am learning grasshopper.

I started with a basic geometry consisting of a parametric triangle. Now I want to copy the triangle so that its copy is side to side with the original.

I want this copying process to be parametric in the way that you can choose how much copies there are, and also that you can choose on what side the next copy will be (if that is even possible).

I found a method where the triangle can be copied, but this method is only suitable if the geometry doesn't rotate (as seen in the picture below).

Thanks in advance!!
