    Lightbulb please help me this question

    use java the Checking the Types of Triangle

    Requirements

    Given a set of (x, y) coordinates representing the vertices of triangles, write a Java program to check the types of all the triangles formed by selecting any three given vertices. The following shows an example displaying all possible triangles formed from 6 vertices.
    1. Write appropriate methods to do the following tasks, one method for each:

    - Given the coordinates of the two vertices of a side of a triangle, calculate its length.
    - Given the length of the three sides of a triangle, calculate its area.
    - Given the length of the three sides of a triangle, check if it is a valid triangle.
    - Given the length of the three sides of a triangle, check if it is right-angled.
    - Given the length of the three sides of a triangle, check if it is isosceles.
    - Given the length of the three sides of a triangle, check if it is scalene.

    2. Input the coordinates of the vertices of triangles from a text file. Each row represents the (x, y) coordinates of a vertex of a triangle, and the two coordinate integers should be read into two integer array representing the x and y coordinates of all vertices. The last row (999, 999) is used to indicate end-of-file and should not be used as formal data.

    An example input text file is shown below:

    vertices.txt
    -5 2
    0 2
    8 2
    8 -11
    4 2
    4 5
    999 999

    3. Using appropriate iterations to select all the triangles formed by choosing any three vertices inputted in (1).

    - For each triangle, check and display its types.

    - Find and display the triangle with maximum area and the one with minimum area. The format of the maximum and minimum area is having 2 decimal places only.

    the format of the output of the program is shown below
    point1 point2 point 3 Types of Triangle

    (-5,2) (0,2) (8,2) Non-triangle
    (-5,2) (0,2) (8,-11) Scalene

    What have you tried?
    Be sure to wrap all posted code in code tags.

    Do you have any specific java programming questions?
    If you don't understand my answer, don't ignore it, ask a question.

    Sorry for this but I can't help you with this because I am looking for the some other help. Actually, I am looking for the some Informative Speech Topics for my speech and I found some good examples of this on topicsmill.com which is an online topic related website and I can choose any topic from this website for my work. I think it will be best for me because I can't trust every service.
