# Triangle
Write a program that can tell you if a triangle is equilateral, isosceles, or scalene.
The program should raise an error if the triangle cannot exist.
Tests are provided, delete one `skip` at a time.
## Hint
The sum of the lengths of any two sides of a triangle always exceeds the length of the third side, a principle known as the _triangle inequality_.
To run the tests simply run the command `go test` in the exercise directory.
If the test suite contains benchmarks, you can run these with the `-bench` flag:
go test -bench .
