Create a ruby class triangle with initalizer, accessors, and member functions for computing the perimeter and the area of arbitrary triangles. make also a member function test that checks sides a, b, and c and classifies the triangle as (1) equilateral, (2) isosceles, (3) scalene, (4) right, and (5) not a triangle. right triangle can be either isosceles or scalene. compute the perimeter and area only for valid triangles (verified by test). show examples of the use of this class.
