# Triangle
Determine if a triangle is equilateral, isosceles, or scalene.
-An _equilateral_ triangle has all three sides the same length.<br/>
+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.)<br/>
+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

+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
There are two different methods of getting set up to run the tests with Objective-C:
- Create an Xcode project with a test target which will run the tests.
- Use the ruby gem `objc` as a test runner utility.
Both are described in more detail here: http://exercism.io/languages/objective-c

### Submitting Exercises
When submitting an exercise, make sure your solution file is in the same directory as the test code.
-For example, if you're submitting `Bob.m` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/objective-c/bob/Bob.m`.
+The submit command will look something like:
+
+```shell
+exercism submit <path-to-exercism-workspace>/objective-c/triangle/Triangle.m
+```
+
+You can find the Exercism workspace by running `exercism debug` and looking for the line beginning
+with Workspace.
