Description
|
|
|
•
|
Three straight lines l1, l2 and l3 are said to be concurrent if they pass through a common point.
|
|
•
|
The routine returns true if l1, l2, and l3 are concurrent; false if they are not; and FAIL if it is unable to determine if the three lines are concurrent.
|
|
•
|
In case of FAIL, if the optional fourth argument cond is given, the condition that makes the lines concurrent is assigned to this argument.
|

•
|
The command with(geom3d,AreConcurrent) allows the use of the abbreviated form of this command.
