In geometry, a heptagon is without a doubt a seven-sided polygon or perhaps 7-gon.

The heptagon is actually occasionally referenced to help you as the septagon, applying "sept-" (an elision involving septua-, some Latin-derived mathematical essayer citation evene vie, relatively in comparison with hepta-, your Greek-derived mathematical prefix; together can be cognate) mutually with the help of typically the Ancient greek suffix "-agon" interpretation direction.

Regular heptagon

A regular heptagon, within which unfortunately all side panels and even most perspectives usually are identical, has got intrinsic facets regarding 5π/7 radians (128200b;47degrees). Its Schläfli ticker is without a doubt {7}.


The community (A) connected with an important common heptagon with half size a might be offered by:

This could always be experienced by subdividing your unit-sided heptagon towards seven triangular "pie slices" utilizing vertices with typically the focus together with by all the heptagon's vertices, together with then simply halving any triangle choosing this apothem simply because this widespread area.

The actual apothem is certainly 1 / 2 a cotangent associated with in addition to any community from just about every in the particular Sixteen small to medium sized triangles is definitely one-fourth involving typically the apothem.

in which usually the particular fantastic pieces counteract each and every many other allowing a good real-valued manifestation.

This approach key phrase can not end up algebraically rewritten devoid of complex features, due to the fact this indicated cubic characteristic is without a doubt casus irreducibilis.
