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.
A very common roof type the hip roof (or hipped roof) does not have flat sides like the gable roof instead all sides of the roof slope down to meet the walls of the house. Building a hip roof is more involved than a gable roof but building the walls for such a house is actually easier as they are all the same height.
