ask the user for the name of the data file

open the data file

if the file fails to open, print an error message and repeat step 1

Skip the first line of the data file

While: read three points

Use a function to calculate the length of each side of the triangle

Use a second function to calculate the area of the triangle

Print the three points and the area of the triangle

After all points have been read.Report

the three vertices for each triangle

the area of each triangle

The maximum area

The minimum area

The average area

Note: Round all output to two decimal places.

Sample Data File:
