(Geometry: area of a triangle) Write a method that returns the area of a triangle using the following header:

public static double getTriangleArea(double[][] points)

The points are stored in a 3-by-2 two-dimensional array points with points[0][0] and points[0][1] for (x1, y1). The triangle area can be computed using the formula in Programming Exercise 2.15. The method returns 0 if the three points are on the same line. Write a program that prompts the user to enter two lines and displays the intersecting point. Here is a sample run of the program:
