I am making a test in geometry. I give two problems on one page, and a TikZ diagram accompanies each problem. I use the vertical spacing command \vskip0.2in to separate the text from the diagram. Why is the text between the text in the second problem and the second diagram much bigger than \vskip0.2in? I use the commands \vfill\pagebreak at the end to "push" everything up. (I apologize for all the code. I didn't want to reduce the code only to have the vertical spacing for the code in my post to be as instructed ... but still have a test with unseemly vertical spacing.)
