TriangleType is a wonderful website that calculates a triangle's type, based on the measurements of it's sides.
To run this you just need a computer that can view local html documents on a web browser.
Open the "triangleType" folder in your file browser of choice, drag the "index.html" icon to your web browser, and away you go!
