Question from the Machine Learning Algorithms test

This property states that the first plane encompasses an amount of inertia equal to the amount of inertia covered by the last axis.

This property states that the first axis encompasses an amount of initial inertia equal to the amount of inertia covered by the last axis.

This property announces that the plane defined by two axes and which carries the maximum variance, compared to any other plane, it must contain the first two axes that we would have found if we had searched for them one by one.
