Regular Properties of a Pentagon. Pentagon ( 5 sided polygon) Hexagon ( 6 sided polygon) Heptagon ( 7 sided polygon) Octagon ( 8 sided polygon) and so on.

Pentagons can be simple or self-intersection. The properties of a simple pentagon (5-gon) are it must have five straight sides that meet to create five vertices, but do not self-intersect: Pentagons have five straight sides Properties. The properties of regular pentagons: All sides are the same length (congruent) and all interior angles are the same size (congruent). Examples include triangles, quadrilaterals, pentagons, hexagons and so on. Some properties of the pentagon are as follows: In the pentagon, the sum of the interior angles is equal to 540°. Furthermore, if the shape is a regular polygon (all angles and length of sides are equal) then you can simply divide the sum of the internal angles by the number of sides to find each internal angle. 540 ÷ 5 = 108°. A polygon is a plane shape (two-dimensional) with straight sides. A famous pentagon is the Pentagon building in Washington, D.C. which houses the Department of Defense. The interior angles of a pentagon add up to 540°, and in a regular pentagon, each angle measures 108°. A regular pentagon has: Interior Angles of 108° Exterior Angles of 72° Area of approximately 1.7204774 × s 2 (where s=side length) Any pentagon has: Sum of Interior Angles of 540° 5 diagonals; Make a Regular Pentagon. Polygons - Hexagons - Cool Math has free online cool math lessons, cool math games and fun math activities. If all the sides are equal and all the angles are of equal measure, then it is a regular polygon. Pentagon Properties. It is an example of a regular pentagon. In the regular pentagon, the interior angle is 108°, and the exterior angle is of 72°. Properties of Regular Polygons Polygon. The sum of internal angles for any (not complex) pentagon is 540°. A pentagon shape is a plane figure, or flat (two-dimensional) 5-sided geometric shape. In this article, let’s discuss the seven-sided polygon called “Heptagon” with proper definition, shape, sides, properties along with its formula in … Really clear math lessons (pre-algebra, algebra, precalculus), cool math games, online graphing calculators, geometry art, fractals, polyhedra, parents and teachers areas too. Otherwise, it is irregular. A regular pentagon is one that has all sides and all angles congruent. You can make a regular pentagon with a strip of paper!
