في الرياضيات، المضلع القابل للإنشاء (بالإنجليزية: Constructible polygon) هو مضلع منتظم يمكن إنشاؤه باستخدام الفرجار والمسطرة. مثلاً، المخمس المنتظم هو مضلع قابل للإنشاء، بينما السباعي المنتظم هو مضلع غير قابل للإنشاء. (ar) En matemàtiques, un polígon construïble és un polígon regular que pot ser construït amb regle i compàs. Per exemple, un pentàgon regular és construible amb regle I compàs mentre que un heptàgon regular no ho és. (ca) In der Mathematik ist ein konstruierbares Polygon ein regelmäßiges Polygon, das mit Zirkel und (unmarkiertem) Lineal – den Euklidischen Werkzeugen – konstruiert werden kann. Zum Beispiel ist das regelmäßige Fünfeck konstruierbar, das regelmäßige Siebeneck hingegen nicht. (de) In mathematics, a constructible polygon is a regular polygon that can be constructed with compass and straightedge. For example, a regular pentagon is constructible with compass and straightedge while a regular heptagon is not. There are infinitely many constructible polygons, but only 31 with an odd number of sides are known. (en) En matemática, un polígono construible es un polígono regular que puede ser construido con regla y compás. Por ejemplo, un pentágono regular es construible con regla y compás mientras que un heptágono regular no lo es. El problema es equivalente a dividir un círculo en partes iguales, lo que se conoce como ciclotomía. (es) Um polígono construtível é um polígono regular que pode ser construído com régua e compasso. (pt) 在数学中，可作图多边形是可以用尺规作图的方式作出的正多边形。例如，正五边形可以只使用圆规和直尺作出，而正七边形却不可以。 (zh) |
