# 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
#
#def triangle(a, b, c)

# return :isosceles if (a == b) || (b == c) || (a == c)
# return :scalene if (a != b) || (b != c) || (a != c)
#end
#def triangle(a, b, c)
# raise TriangleError, "My Message" if a+b+c < 3
# raise TriangleError, "My Message2" if a+b-c (<0 || != a || !=b)
