Which roof type is defined by a triangular end wall and a roof that slopes down on two sides?

• A. Hip
• B. Shed
• C. Pavilion
• D. Gable

Answer: (D)

The key feature here is a roof that forms a triangle at the end of the building. When the roof slopes down on two opposite sides and meets a ridge, the end wall above the eaves forms a triangular shape called a gable. That combination—two sloping roof planes on opposite sides plus the triangular end wall—defines a gable roof. A hip roof, by contrast, slopes on all four sides and doesn’t create a triangular end wall. A shed roof is a single, uniform slope with no triangular end, and a pavilion roof isn’t defined by this two-slope, triangular-end pattern.
