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].
