A gable roof is defined as which?

• A. A type of roof containing sloping planes of the same pitch on each side of the ridge. Contains a gable at each end.
• B. A roof with two different slopes on each side of the ridge.
• C. A roof with curved eaves.
• D. A flat roof.

Answer: (A)

A gable roof is defined by two sloping planes that meet along a central ridge, forming triangular end walls called gables. That description matches a roof with sloping planes on each side of the ridge at the same pitch and with a gable at each end. The other options describe shapes that don’t define a gable roof: one describes asymmetrical slopes on the two sides, one mentions curved eaves, and one describes a flat roof with no slope. So the correct choice is the one that captures the standard geometry of a gable roof.
