Which roof type is characterized by triangular end walls and a ridge?

Explanation:
Identify a roof by its end walls and ridge. A roof with triangular end walls and a ridge is a gable roof. In a gable roof, two roof planes slope down from a central ridge, creating the triangular ends called gables. This configuration clearly shows a ridge at the top. The other options don’t fit: a flat roof has no ridge, a dome roof is curved all around, and a mansard roof has two slopes on each side with a flat top and lacks those simple triangular ends.
