$2.$ Do They Belong?

A triangle formed by the three points $a(x1,y1),b(x_2,y_2)$ and $c(x3,y_3)$ is a non$-$degenerate triangle if the following rules are respected is the length of the line between points a and $b)$:

$|ab|+|bc|>|ac|$

$|bc|+|ac|>|ab|$

$|ab|+|ac|>|bc|$

A point belongs to a triangle if it lies somewhere on or inside the triangle. Given two points $,yp$ and $q=(xq,yq),$ return the correct scenario number:

$0$ : If the triangle abc does not form a valid nondegenerate triangle.

$1$: If point $p$ belongs to the triangle but point $q$ does not.

$2$: If point $q$ belongs to the triangle but point $p$ does not.

$3$: If both points $p$ and $q$ belong to the triangle.

$4$: If neither point $p$ nor point $q$ belong to the triangle.
