The basic roof frame for a gable roof forms how many right triangles?

In a gable roof, the basic roof frame consists of two sloping sides that meet at a ridge. Each side of the roof can be visualized as forming a right triangle when you look at it in cross-section. Each triangle is created by drawing a vertical line from the peak (the ridge) down to the bottom edge (eave) of the roof, which serves as one leg of the triangle, while the slope of the roof becomes the hypotenuse.

Since there are two slopes on a gable roof (one on each side of the ridge), this design results in a total of two right triangles. Understanding the geometry here is crucial for accurately determining roof framing, ensuring structural integrity, and facilitating proper material calculations during construction.
