Calculate the area of a triangle between three points:
these three points are the vertices of the triangle.
The test suite checks for equality, but different techniques have small numerical differences. The test suite should allow for these differences, as it eliminates many solutions that are correct.
This problem has been updated to check against a small error value rather than for equality.
