The British Flag Theorem is a geometric theorem that relates to specific points in a rectangular configuration. It states that for any rectangle \\( ABCD \\) and any point \\( P \\) in the plane, the sum of the squared distances from point \\( P \\) to two opposite corners of the rectangle is equal to the sum of the squared distances from \\( P \\) to the other two opposite corners.
