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.
What does a regular polygon look like?
To be a regular polygon, the flat, closed, straight-sided shape must also have another property. Every interior and exterior angle in the regular polygon is equal to every other interior and exterior angle, and every side is equal in length to every other side. A regular polygon has: Straight sides.
What is polygon example?
In simple mathematics, a polygon can be any 2-dimensional shape that is formed with straight lines. Be it quadrilaterals or triangles and pentagons, these are all perfect examples of polygons. For example, a triangle has three sides, and a quadrilateral has four sides.
How do you identify a polygon?
A polygon is a two-dimensional closed figure that has three or more straight sides. Any figure with straight edges, such as a triangle or rectangle, is a polygon. Figures that have any curved sides or open sides are not classed as polygons.
How many sides is a polygon?
Other Types of Polygons Polygon Number of Sides Quadrilateral 4 Pentagon 5 Hexagon 6 Heptagon 7.
What are the 12 kinds of polygon?
They are: Regular Polygons. Irregular Polygons. Concave Polygons. Convex Polygons. Trigons. Quadrilateral Polygons. Pentagon Polygons. Hexagon Polygons.
What is not a polygon?
A circle is not a polygon. A figure or shape is not considered a polygon if it has rounded sides or if its sides intersects at any place other than at the ends of each side. Therefore a circle is not a polygon and an hourglass shape is not a polygon. Instead, it is two polygons, two triangles.
What is a polygon for kids?
Any closed two-dimensional shape with three or more sides is called a polygon. Polygons can be regular or irregular. The sides and angles of a regular polygon are all equal. An irregular polygon has at least two sides or two angles that are different.
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.
How do you make a polygon?
Draw a polygon using custom polygon Click Polygon. Place the pointer on the map and click the location of the first point to start drawing. Move the pointer to the next point and click. Continue clicking at each corner of the shape until you have created the polygon. Note: Double-click the first point to stop drawing.
What are 3 characteristics of a polygon?
Properties of Polygons The number of sides of the shape. The angles between the sides of the shape. The length of the sides of the shape.
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.
Is a quadrilateral A polygon?
A quadrilateral is a polygon with four sides. There are many special types of quadrilateral. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel .
How much sides does a pentagon have?
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 is a polygon grade 2?
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is “closed” (all the lines connect up).
What is a 1000000000000000 sided shape called?

What is a shape with 1 trillion sides?

What is the most sides a polygon can have?
In geometry, a myriagon or 10000-gon is a polygon with 10,000 sides. Several philosophers have used the regular myriagon to illustrate issues regarding thought.
Are ovals polygons?
The circle and oval are not polygons, which means their area and perimeter are calculated differently.
Is a kite a polygon?
A kite is a polygon with four total sides (quadrilateral). The sum of the interior angles of any quadrilateral must equal: degrees degrees degrees.
What is a polygon with 10 sides?
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.
How do you teach polygons?
Introducing polygons Draw a regular pentagon and an irregular pentagon on the board. Get your students to count the sides and corners. Ask if the sides are the same length on both shapes. Emphasize that shapes with 5 sides are pentagons, but if the sides and corners are not equal it is an irregular pentagon.
How do you describe a polygon?
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.
What is a polygon for 3rd grade?
What are Polygons? Polygons are closed, 2D shapes that have only straight sides. Shape 1 is a closed, flat shape. It’s also made up of straight lines (line segments) only. We call Shape 1 a polygon!.
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 8 sides?
Regular octagon Regular octagon Type Regular polygon Edges and vertices 8 Schläfli symbol {8}, t{4} Coxeter–Dynkin diagrams.
What is a polygon with 5 sides called?
A pentagon is a five-sided polygon. A regular pentagon has 5 equal edges and 5 equal angles.
How do you illustrate a polygon?
For example: You can draw a regular polygon using a circle. You can draw a square. You can draw a regular pentagon, with five equal sides/angles. You can draw a regular hexagon, with six equal sides/angles. You can draw a regular octagon, with eight equal sides/angles.
How do you draw a simple polygon?
To draw a polygon, follow these steps: Select the Polygon tool. Click in the drawing area to place the polygon’s center point. (Optional) By default, polygons have 5 sides. Move the cursor in or out from the center point to size the polygon and click to finish the shape.
