The angle at which the wings are slanted upward from the root to the tip is called what?

Explanation:
Dihedral is the upward angle of the wings from the root to the tip. This arrangement gives the airplane lateral stability: if the aircraft tilts to one side in a gust or during a sideslip, the lower wing develops more lift than the higher wing, creating a restoring roll that brings the wings back level. The other terms describe different wing geometries—sweepback is the backward tilt of the wing's leading edge, anhedral is downward-sloping wings, and torsion refers to twisting of the wing along its span. So the upward slant from root to tip is called dihedral.
