Create a class called Point which can be used to set and get a point (x, y) on a X-Y coordinator. Write a program to let your client set any three points to define a triangle on the X-Y plane and determine:-

1. what type of triangle formed by client’s three points, e.g. right angle triangle, isosceles triangle and equilateral triangle,

2. whether the three points are collinear (three points are on the same line),

3. area of the triangle if the three points are not collinear.

Hello Everyone! I'm new here. I'm quite bad at my OOP, and the above is a qn i gotta work on. I'm extremely bad at CLASS, I'm not sure how to go abt with it. I still tried using it and the above is what i got. The progam works well but i'm not sure the CLASS part is right so do help mi please.
