How do I snap an edge/vert to a another vert in edge slide mode?

[cr2290]

Hi there,

I'm trying to slide an edge to another vert in edge slide mode so that the angle of the other faces stay the same, but when I try to snap it, it overextends or doesn't snap at all.

I'd like it to look like this in the end, albeit the faces should be flush with each other so it's all one flat plane.

I need both cuboids to still be at the same angle, but I'm stumped on how to make sure it stays that way.

You cant. But you could rotate the gizmo. Hold down D and click onto the edge.
