1) Find the longest side of the triangle (one way is define normalized direction vectors for each line and then take inner products to find the largest angle)

2) Redefine the coordinate system so that the longest side of the triangle is on the new x-axis. Notice that the triangle is now above or below the new x-axis. Also since the longest side is on the axis, both of the angles opposite to the other two sides are acute.

4) Determine if the point is above or below the new x-axis.

5) If it above the new x-axis, it needs to be below the other two lines (in the new coordinate system). If it below the new x-axis, it needs to be above the other two lines (in the new coordinate system).
