Yep - Or you could add a filler at the top edge.

I have a sheetrocked attic in which I would like to install a knee
wall. I am using steel studs. What is the proper procedure to
eliminate the triangular space about the top metal track?

You could cut the top ends of the studs to match the angle of the
ceiling and bend the 2 flanges on the track to match if you're using
the light duty steel.
