- ArePerpendicular( <Line>, <Line> )
- Decides if the lines are perpendicular.
- Normally this command computes the result numerically. This behavior can be changed by using the Prove command.
- Example:
ArePerpendicular(Line((-1, 0), (0, -1)), Line((0, 0),(2,2)))
yields true since the given lines are perpendicular.
