ピタゴラス学的な
解説 Definition
Pythagorean は、古代ギリシャの数学者・哲学者ピタゴラス、または彼の名に関連する考え方や数学に関する形容詞です。特に Pythagorean theorem（ピタゴラスの定理）のように、直角三角形の辺の関係を述べる数学用語でよく使われます。
Pythagorean means relating to the ancient Greek philosopher Pythagoras, his followers, or ideas associated with them. In mathematics, it most commonly appears in terms such as the Pythagorean theorem, which states the relationship among the side lengths of a right triangle.
覚え方のコツ Memory Tip
Pythagorean は人名 Pythagoras に形容詞語尾 -ean が付いた語で、通常は固有名由来のため大文字で始めます。最重要の組み合わせは Pythagorean theorem「ピタゴラスの定理」。直角三角形の a²＋b²＝c² と結び付け、数や調和を論じた学派にも使うと覚えます。
Build the word from Pythagoras plus the adjective ending -ean, meaning related to a person or their school of thought. Because it comes from a proper name, Pythagorean is normally capitalized. Anchor it to the familiar phrase “Pythagorean theorem” and the right-triangle formula a² + b² = c². Then extend the association beyond geometry: Pythagorean can also describe the ancient philosophical movement concerned with numbers, music, harmony, and the structure of the universe. This broader use distinguishes the adjective from the theorem alone.

pythagorean の語源・成り立ち Etymology
古代ギリシャの数学者・哲学者Pythagoras（ピタゴラス）に由来。名前はギリシャ語のPythō（デルポイの古名）とagoras（集会・広場、agoraから）に分解でき、「ピュトーの広場の人」の意。関連語：Pythagorean theorem（ピタゴラスの定理）。直角三角形の定理で有名だが、元は音楽や宇宙の数的調和を説いた哲学学派の名。
Pythagorean is formed from the Greek personal name Pythagoras and an adjectival suffix meaning belonging or relating to. It entered English through Greek and Latin forms used for Pythagoras's followers and doctrines. The word can therefore refer both to the ancient philosophical school and to mathematical ideas traditionally associated with Pythagoras, especially the theorem concerning the sides of a right triangle. The personal name itself is ancient and its exact formation is not stated with certainty here.
