Ancient Greek mathematicians struggled with three geometric construction problems:They were unable to solve any of these problems using the traditional Euclidean ruler-and-compass tools. However, they did solve all three using so-called “mechanical methods”. We shall discuss the history of these three problems and present two mechanical solutions.

- Trisect an arbitrary angle
- Square the circle (i.e., given a circle, construct a square having the same area)
- Double the cube (i.e., given a cube, construct another cube having twice the volume)
