Sen. Obama, who has taught courses in constitutional law at the University of Chicago, has regularly referred to himself as a constitutional law professor, most famously at a March 30, 2007, fundraiser when he said, I was a constitutional law professor, which means unlike the current president I actually respect the Constitution..
Hip roof. A hip roof, hip-roof or hipped roof, is a type of roof where all sides slope downwards to the walls, usually with a fairly gentle slope. Thus it is a house with no gables or other vertical sides to the roof. A square hip roof is shaped like a pyramid.
The triangular faces of the roof are called the hip ends, and they are bounded by the hips themselves. The hips and hip rafters sit on an external corner of the building and rise to the ridge. Where the building has an internal corner, a valley makes the join between the sloping surfaces.
