How do you dimension a diameter on a line?!

Fundamentals 3 - Exercise: Coffee Cup
Fallen at the first hurdle here. I can't figure out how to dimension this 125 diameter. It's a line. How do I go beyond the line to change the dim to a diameter?
I've read the hint, and I still haven't figured it out.

    Place the dimension text on the other side of the centreline as shown in the picture.

    Got it. 'To the vertex indicated' threw me. Started to think was it the blue vertex, seeing as all the other vertices were black.

    OK. Can you tell me what's going on here? Why the slanted dimension line?

    Double check if your centerline is vertical. Hit show constraints in the dialog and check for the vertical constraint. I think the dimension is slanting to follow the line angle. I cant see what else it would be following.

    I just redrew it in the end. Both lines were horizontal.
