More than Four Sides
A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… The names of polygons are derived from the prefixes of ancient Greek numbers.
What are polygon sides?
A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two others sides but only at their endpoints. The sides must be noncollinear and have a common endpoint. A polygon is usually named after how many sides it has, a polygon with n-sides is called a n-gon.
Which polygon has 4 sides?
Definition: A quadrilateral is a polygon with 4 sides. A diagonal of a quadrilat- eral is a line segment whose end-points are opposite vertices of the quadrilateral.
What is a polygon that has 5 sides?
A pentagon is a polygon that has 5 sides and 5 vertices.
What polygon has 9 sides?
A nine-sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners, or vertices. The word “nonagon” comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.
What is a polygon class 8?
A polygon is a simple closed curve made up of line segments only. Polygons are classified according to the number of sides they have. What are Adjacent Sides? If the two sides of a polygon have a common vertex then they are called the adjacent sides of the polygon.
What is a polygon Class 6?
A polygon is a closed figure formed of three or more line segments. Examples of polygons are triangle, quadrilateral, pentagon and. hexagon.
What is the polygon that has 11 sides?

What type of polygon has 12 sides?
A 12 sided shape is a polygon called a dodecagon.
What is a polygon with 12 sides called?
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
What is a polygon with 10 sides 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.
