Which term describes a framework of rafters, posts, and struts supporting a roof?

Explanation:
A truss is a framework of members that form triangles to support a roof. The idea is that triangles are inherently stable, so when the roof load pushes down, those forces travel along the interconnected members to the supports at the walls or columns, distributing weight efficiently and reducing bending in any single piece. This makes the roof strong yet lightweight, and allows for longer spans than a simple beam-and-rafter setup. The other terms describe roofing material or actions, not the structural network that carries the roof, so they don’t fit as the term for this framework.
