## Details

The generalization of the caption is a theorem that two parallelograms of the same base and the same altitude can be decomposed into parts, where , is the altitude of the common part of the parallelograms (the red triangle) and .

Here denotes the least integer not less than the real number (the ceiling function) [1, pp. 127, 128].
