Write down the theorem of perpendicular axes of moment of inertia

The perpendicular axis theorem asserts that the moment of inertia of a planar lamina (i.e. 2-D body) at an axis perpendicular to the plane of the lamina is equal to the sum of the moments of inertia of the lamina around two axes at right angles to each other, intersecting each other at the point
