# 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

a single line. Feel free to add your own code/tests to check for degenerate triangles.
-## Making the Test Suite Pass
-1. Get [PHPUnit].
+## Running the tests
+
+1. Go to the root of your PHP exercise directory, which is `<EXERCISM_WORKSPACE>/php`.
+ To find the Exercism workspace run
+
+ % exercism debug | grep Workspace
+
+1. Get [PHPUnit] if you don't have it already.
+
% wget --no-check-certificate https://phar.phpunit.de/phpunit.phar
% chmod +x phpunit.phar
-2. Execute the tests for an assignment.
+2. Execute the tests:
