AreConcurrent Command
From GeoGebra Manual
 |
This page is about a feature that is supported only in GeoGebra 5.0. |
 Warning: | This GeoGebra command is heavily under construction. Expect to encounter various problems when trying it out. The syntax or the output of this command may be subject to change. |
- 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). Note: See also AreCollinear, AreConcyclic, AreEqual, ArePerpendicular, AreParallel commands.
