A polygon has exactly the same number of both internal and external angles to the number of sides. Assuming external angles count, there are two times the number of sides as the total number of angles

A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
There is no such thing as an exterior polygon. "Exterior" means outer. Polygons can have exterior angles, but that is about it!A regular polygon can have 3 or more sides - up to infinitely many.There is no such thing as an exterior polygon. "Exterior" means outer.

A polygon is any plane figure bounded only by straight lines. A triangle is therefore a polygon with three sides and a pentagon is a polygon with five sides. A convex polygon has no interior angle greater than 180° . A re-entrant polygon has at least one interior angle greater than 180° . A regular polygon has all its sides and angles equal. The sum of the interior angles of a polygon is 2n - 4 right angles (n is the number of sides). The sum of the exterior angles of a convex polygon is 360° .
A - heptagon - is a polygon with seven straight sides and 7 angles.-- note --Some people also use the word - septagon - for this polygon, but the other word is more widely recognised internationally.
A polygon can have 8 sides but does not have to. The word "Polygon" is made up of two words: "poly-" and "-gon" which have Greek roots which mean "many" and "angle" respectively; literally a "polygon" is a "many angled shape". A polygon is any shape that has 3 or more sides. An 8 sided polygon is called an octagon (literally "eight angles").
