A developable surface is a type of surface in geometry that can be flattened into a two-dimensional plane without distortion. This means that the surface can be "unfolded" or "rolled out" in such a way that there is no stretching, tearing, or compressing involved. Developable surfaces include shapes like: 1. **Planes**: Flat surfaces are obviously developable as they are already two-dimensional.
