Chapter 2, Problem 2PP

In this project, you will perform calculations with triangles. A triangle is defined by the x- and y-coordinates of its three corner points.

Your job is to compute the following properties of a given triangle:

• the lengths of all sides
• the angles at all corners
• the perimeter
• the area

Supply a program that prompts a user for the corner point coordinates and produces a nicely formatted table of the triangle properties.
