A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The orange shape is still a polygon even if it looks like it has an arrow. All the sides are straight, and they all connect.
How does a polygon look like?
A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.
How many sides do polygon have?
Other Types of Polygons Polygon Number of Sides Triangle 3 Quadrilateral 4 Pentagon 5 Hexagon 6.
What is a polygon with 4 sides?
Definition: A quadrilateral is a polygon with 4 sides. Definition: A parallelogram is a quadrilateral where both pairs of opposite sides are parallel.
What does a Pentagon look like?
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. Pentagon An equilateral pentagon, i.e. a pentagon whose five sides all have the same length Edges and vertices 5 Internal angle (degrees) 108° (if equiangular, including regular).
What are the parts of a polygon?
The parts of polygons include the sides, interior angles and exterior angles. There is also the vertex, the spot where two sides meet, and the diagonals, or lines connecting vertices.
How do you find a side of a polygon?
Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15. Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon.
Can a polygon have curved sides?
A polygon is geometric shape that is made up of straight line segments. Polygons cannot contain any curved sides, or holes. For example, a square is a polygon but a circle is not. Polygons can have any number of sides and angles, but the sides cannot be curved.
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. 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 with 5 sides and 5 angles?
A pentagon is a shape with 5 sides and 5 angles. An octagon is a shape with 8 sides and 8 angles.
What is a polygon with 6 sides and 6 angles?
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°.
Is a starfish A Pentagon?
Starfish: Almost all starfish have a fivefold radial symmetry or are shaped like pentagons.
Is a triangle a polygon?
Triangles are polygons with three sides. Quadrilaterals are polygons with four sides. Pentagons are polygons with five sides. Hexagons are polygons with six sides.
What are the 3 main components of polygons?
Polygon terminology Polygons are straight-sided shapes (3 or more sides), defined by three-dimensional points (vertices) and the straight lines that connect them (edges). The interior region of the polygon is called the face. Vertices, edges, and faces are the basic components of polygons.
How many polygons are there?
There are two main types of polygon – regular and irregular. A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides.
Which figure is a polygon?
A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.
Can polygons be concave?
A concave polygon is a polygon that is not convex. An example of a non-simple (self-intersecting) polygon is a star polygon. A concave polygon must have at least four sides.
How do you measure a polygon?
The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.
What is a polygon perimeter?
The total distance of the outer sides of a closed figure is known as the perimeter. It is the total length of all sides of a polygon. Perimeter = Sum of all sides. The unit of the perimeter of any polygon will remain the same as the unit of its respective sides.
Is a circle a polygon?
Complete step-by-step answer: A circle is not a polygon. A polygon is a closed figure on a plane formed from a finite number of lines segments connected end-to-end. As a circle is curved, it cannot be formed from line segments, as thus does not fit the conditions needed to be a polygon.
Can a polygon be a 3d shape?
A three-dimensional shape whose faces are polygons is known as a polyhedron. This term comes from the Greek words poly, which means “many,” and hedron, which means “face.” So, quite literally, a polyhedron is a three-dimensional object with many faces.
What do you call a polygon with 12 sides?
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 200 sided shape called?
What is the name of a polygon with? # Name of the Polygon + Geometric Drawing 200 sides dihectogon 300 sides trihectogon 400 sides tetrahectogon 500 sides pentahectogon.
What is the polygon with 11 sides called?
In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka “eleven” and –gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.).
What objects are pentagon shaped?
Examples of Pentagons The famous U.S. department of defense building in Washington D.C. (The Pentagon building) The home plate on a baseball field. School crossing signs. Sections on a soccer ball.
What is pentagon in math?
A pentagon is a polygon with 5 sides and 5 angles. The word “pentagon” is made up of two words, namely Penta and Gonia, which means five angles. All the sides of a pentagon meet with each other end to end to form a shape.
How many sides does a pentagon have answer?
Answer- The Pentagon has 5 (five) sides. A pentagon is a five-sided polygon also known as 5-gon in geometry. 540° is the sum of internal angles of a simple pentagon.
