I can't seem to figure out the right term, but basically I have a mesh like this:
and I want to make a face, but when I press F I get a triangle like this:
When I want it to make a quad like this:
Is there some easy way to do this? My process is usually making the face, subdividing the triangle edge, manually copying the coordinates of the vertex I want to line it up with, and then moving the vertex via entering the coordinates. Is there some kind of 'make vertex where these two edges will intersect' function that I'm missing? I feel like I'm doing this the incredibly long way.
