More than Four Sides A five-sided shape is called a pentagon . Interior angle of any regular polygon =180[(n−2)/n] Interior angle of any regular Icosagon = 180(20 – 2)/20 = 162° The sum of all the interior angles of a regular Icosagon is 3240°.
How do you describe a pentagon?
In geometry, a pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to 540° . A pentagon shape is a plane figure, or flat (two-dimensional) 5-sided geometric shape.
Is there a 5-sided shape?
In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting.
What is a shape with 100 sides called?
In case of two dimensional shapes, a shape with 100 sides is called Hectogon . ... Polygons are usually named according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, e.g. poly (means many) and gon (means sides).
How does a pentagon look?
A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles , which add up to 540°.
What is a 1000000000000000 sided shape called?
1000000000000000 sided shape are often used in geometry, an octadecagon ( or octakaidecagon ) 11-gon .
What’s a 6 sided shape called?
In geometry, a hexagon (from Greek ἕξ, hex, meaning “six”, and γωνία, gonía, meaning “corner, angle”) is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.
What is 10 sided shape called?
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
What is a 7 sided shape called?
In geometry, a heptagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using “sept-” (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix “-agon” meaning angle.
What’s a 9 sided shape?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

Is a starfish A pentagon?
Starfish: Almost all starfish have a fivefold radial symmetry or are shaped like pentagons .
Can a pentagon have 4 right angles?
Sum of Interior Angles = 540′. Four right angles would leave 180′, which is impossible. So a pentagon has a maximum of three right angles , as shown. ... 6 right angles = 540′, leaving 360′, which is impossible.
Is a house shape a pentagon?
The roof can be two slanted sides and the other three sides will make up the walls and floor of a house . Remember, a pentagon can look many different ways, but the simplest way to draw one is just to remember what a house looks like.
