- 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.
Note: See also AreCollinear, AreConcurrent, AreConcyclic, AreEqual, AreParallel commands.
