What's the difference between i.e. and e.g.?
roof that slopes upward from all sides of a structure, having no vertical ends. The hip is the external angle at which adjacent sloping sides of a roof meet. The degree of such an angle is referred to as the hip bevel. The triangular sloping surface formed by hips that meet at a roof's ridge is called a hip end. A pyramidal hipped roof, also known as a pavilion roof, is hipped equally at all corners and the hips meet at a single peak, but the more common form of hip roof is above a rectangular structure, where a roof ridge meets two hips at either end
