# Triangle
|
||
|
|
|
||
|
|
Welcome to Triangle on Exercism's C# Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
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.
