In geometry, a pentagon (from Greek πέντε (pente) 'five', and γωνία (gonia) 'angle' [1]) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°.
A pentagon is a 5-sided Polygon (a flat shape with straight sides): Regular or Irregular. When all angles are equal and all sides are equal it is regular, otherwise it is irregular: Concave or Convex. A convex pentagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°.
Pentagon Shape A pentagon shape is a 5 sided polygon. This five sided shape has five straight sides and five interior angles, which add up to 540°. Let us learn more about the pentagon shape, the pentagon properties, pentagon shape objects, and some pentagon shape examples in this article.
2023年8月3日 · A pentagon is a closed and flat geometrical shape having five straight sides and five angles. The word ‘pentagon’ came from the Greek word ‘pente’ meaning ‘five’ and ‘gonia’ meaning ‘angle’. When all the five sides and angles of a pentagon are equal, it is called a regular pentagon. Otherwise, it is an irregular ...
The total length of the five sides of a regular or irregular polygon is called its perimeter. Perimeter of a pentagon = (side 1 + side 2 + side 3 + side 4 + side 5) units. The perimeter of a regular five sided shape equals (5 x side) units if all the sides have the same measurement.
2023年5月29日 · The Pentagon is a geometric shape that is characterized by its five sides and five angles. It is a polygon, which means it is a closed figure formed by connecting straight-line segments. The term “pentagon” is derived from the Greek words “penta,” meaning “five,” and “gonia,” meaning “angle.”
2017年3月21日 · A pentagon is a geometric shape with five sides and five angles. In a regular pentagon, all sides are of equal length and all angles are equal, each measuring 108 degrees. Pentagons can be found in various contexts, from architecture and design to natural forms.
Pentagon shape. A pentagon is a five-sided polygon; there are a few different pentagon shapes.
