🧄Why a Cube's Diagonal Angle Never Changes

The angle between any two space diagonals of a cube is a constant value of approximately $70.53^{\circ}$, irrespective of the cube's size. This is proven using vector analysis, specifically the dot product, where the side length cancels out, leaving a fixed ratio for $\cos (\theta)$ as 1 / 3. The interactive demonstration feature provides a visual and numerical way to confirm this unchanging principle.
