To stack the odds in our favor we therefore need to take into account each one of the three methodologies and hopefully find them to be congruent, meaning that they all point in the same direction.

In the matching process the parameters of rotation and displacement were obtained by two congruent triangles, then the point-pairs matching would be performed on the transformed sets.

The invention also relates to a method for measuring the heat conduction coefficient, the eutectic point and the congruent melting point by the device.
