Detailed description of the triangle tool
The length of the sides range from three to nine centimetres. The body of the triangle is about 12 millimetres wide. On all three of the outer sides a finger fitter is provided for easy lifting or extra grip. One outer corner is rounded, the other two are sharp. All three corners have a pushpin marker at the top surface.
Along the outside and inside are indents located at every centimetre. They align with each other. In case the length of the side is odd numbered, there is an indent in addition at the halfway position.
