# Triangle Determine if a triangle is equilateral, isosceles, or scalene. An _equilateral_ triangle has all three sides the same length. An _isosceles_ triangle has at least two sides the same length. (It is sometimes specified as having exactly two sides the same length, but for the purposes of this exercise we'll say at least two.) A _scalene_ triangle has all sides of different lengths. ## Note For a shape to be a triangle at all, all sides have to be of length > 0, and the sum of the lengths of any two sides must be greater than or equal to the length of the third side. See [Triangle Inequality](https://en.wikipedia.org/wiki/Triangle_inequality). ## Dig Deeper The case where the sum of the lengths of two sides _equals_ that of the third is known as a _degenerate_ triangle - it has zero area and looks like a single line. Feel free to add your own code/tests to check for degenerate triangles. ## Setup Follow the setup instructions for Crystal here: http://exercism.io/languages/crystal More help installing can be found here: http://crystal-lang.org/docs/installation/index.html ## Making the Test Suit Pass Execute the tests with: ```bash $ crystal spec ``` In each test suite all but the first test have been skipped. Once you get a test passing, you can unskip the next one by changing `pending` to `it`. ## Source The Ruby Koans triangle project, parts 1 & 2 [http://rubykoans.com](http://rubykoans.com) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
