# Triangle Project Code.
# Triangle analyzes the lengths of the sides of a triangle
# (represented by a, b and c) and returns the type of triangle.
#
# It returns:
# :equilateral if all sides are equal
# :isosceles if exactly 2 sides are equal
# :scalene if no sides are equal
#
# The tests for this method can be found in
# about_triangle_project.rb
# and
# about_triangle_project_2.rb
#

# Error class used in part 2. No need to change this code.
