Geometry has established that given an accurate measurement of two sides of a triangle, and an accurate measurement of the angle between these two known sides, it is possible to compute the length of the third side.
By incorporating the radius of the throwing arc or throwing circle into the calculations that it does, Precision Athletics machines are able to accurately measure an athlete’s performance without venturing into the throwing area to make the measurement.
An athlete’s performance is computed as shown below in the diagram by using data that was entered prior to the start of the competition – the Precision Athletics machine and the radius of the throwing circle or arc.
