What is the point at which the top of a triangle meets the ridge?
Through geometry, the infill triangle of roof, with its two bottom corner positions fixed by the wall extents, will be set back to incline at the same degree as the two preexisting sides. The point at which the top of the triangle meets the ridge forms a Y shape, which if viewed (in this case upside down) from above, resembles the body & two legs of a stick man drawing. Thus the point at which they meet is called the hip. If both the ends are done this way, or if the house has another perpendicular roof due to the building floorplan being T shaped, they are often referred to as double hips.
