While handling a project, the landscaper is asked by the owner of the mansion that he wants four trees in front of his mansion that are exactly equidistant from each other.
How will he do it?
He will have to form the shape of a tetrahedron. This means that, he will plan three trees on the vertices of an equilateral triangle and then plant one at the exact center. In this way, all the trees will be equidistant from each other.
