AreConcurrent Command

AreConcurrent( <Line>, <Line>, <Line> )

Decides if the lines are concurrent. If the lines are parallel, they considered to have a common point in infinity, thus this command returns true in this case.

Normally this command computes the result numerically. This behavior can be changed by using the Prove command.

Example: AreConcurrent(Line((1, 2), (3, 4)), Line((1, 2), (3, 5)), Line((1, 2), (3, 6))) yields true since all three lines contain the point (1,2).
