Solve using geogebra or any other software Considering the set of points A = (-1, 6), B = (-1, -1), C = (4, 7), D = (6, 7), E = (1, 1), F = (-5, 3), P = (2, 3), Q = (2 , 3), identify the value of the parameter for which we have the smallest value of the length of minimal spanning tree associated (explain, in few sentences, the solution).
