Ladder in the Hallway Problem

Have you ever tried to move a large piece of furniture through a narrow hallway and found yourself stuck? Here we'll explore the classic problem: what is the longest ladder/piece of furniture that can make it around the corner in this hallway? Controls
  • Use the sliders for a and b to adjust the widths of the hallways.
  • Drag point C to move the ladder through and see the longest possible ladder for that position.
