Abstract
Suppose that \(T(\alpha , \beta )\) is an obtuse triangle with base length 1 and with base angles measuring \(\alpha \) and \(\beta \) (where \(\alpha >90^{\circ }\)). Let S be a square with a side parallel to the base of \(T(\alpha , \beta )\) and let \(\{S_{i}\}\) be a collection of the homothetic copies of S. In this note a tight upper bound of the sum of the areas of squares from \(\{S_{i}\}\) that can be parallel packed into \(T(\alpha , \beta )\) is given. This result complements the previous upper bound obtained for \(\alpha \le 90^{\circ }\).
