In a Computer Based Tutor $($CBT$)/$ Intelligent Tutoring System $($ITS$)$ using AI in Math, consider the following. In any valid triangle XYZ $($with points $x,Y$ and $Z,$ forming sides $xY,YZ$ and $xZ)$ it is mandatory that:

$xY+YZ>xZ,$

$xY+xZ>YZ,$

$YZ+xZ>xY$

This is an example of:

Unary constraints

Higher order contraints

Binary constraints

No constraints

Question $16$

$2$ pts

With reference to the previous question $($Q$15),$ which of the following would NOT be a valid triangle?

$xY=5,YZ=6,xZ=7$

$xY=15,YZ=15,xZ=6$

$xY=10,YZ=10,xZ=10$

$xY=3,YZ=4,xZ=15$
