ab: Downtown Toronto is filled with public art and interesting architecture and
makes a wonderful location for a Math Trail. In one building, there are
a series of ladders leaning against a wall. As part of the Math Trail,
one of the authors posed the following problem to his students: “Walk
over to one of the ladders that is leaning against the wall at an
angle. If you were able to move this ladder at the base, so that it
became 10 centimeters further from the wall, would the top of the
ladder slide down the wall through a distance of 10 centimeters?”
