 Question: can you have a heart attack from laughing Context: There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be regarded as trapezoids. Some define a trapezoid as a quadrilateral having only one pair of parallel sides (the exclusive definition), thereby excluding parallelograms. Others define a trapezoid as a quadrilateral with at least one pair of parallel sides (the inclusive definition), making the parallelogram a special type of trapezoid. The latter definition is consistent with its uses in higher mathematics such as calculus. The former definition would make such concepts as the trapezoidal approximation to a definite integral ill-defined. This article uses the inclusive definition and considers parallelograms as special cases of a trapezoid. This is also advocated in the taxonomy of quadrilaterals.

The most important wizards were Gandalf the Grey and Saruman the White. Gandalf remained true to his mission and proved crucial in the fight against Sauron. Saruman, however, became corrupted and sought to establish himself as a rival to Sauron for absolute power in Middle-earth. Other races involved in the struggle against evil were Dwarves, Ents and most famously Hobbits. The early stages of the conflict are chronicled in The Silmarillion, while the final stages of the struggle to defeat Sauron are told in The Hobbit and in The Lord of the Rings.
