What is an octagon for kids?

An octagon is a shape that has eight sides, which gives it eight angles. (Angles happen whenever two straight lines meet!) An octagon can also be called a polygon because it has straight sides and is a flat shape, not a 3-D shape like a ball.

What are the 5 properties of a octagon?

Properties of Octagon

  • These have eight sides and eight angles.
  • All the sides and all the angles are equal, respectively.
  • There are a total of 20 diagonals in a regular octagon.
  • The total sum of the interior angles is 1080°, where each angle is equal to 135°(135×8 = 1080)

How did the octagon get its name?

An octagon is a polygon with 8 sides and 8 interior angles. The word ‘Octagon’ is derived from the Greek word, ‘oktágōnon’ which means eight angles. That is the reason why it is called an octagon.

What is a fact about an octagon?

An octagon has 8 exterior angles. The sum of the exterior angles of an octagon is 360°. Regular octagon: An octagon in which all sides and angles are equal. Each angle of a regular octagon is 135°.

How many points does a octagon have?

In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges….Symmetry of octagon.

How many sides does an octagon have?

8 sides
An octagon is a polygon made up of 8 sides. It has eight angles. Octagon = Octa + gon where octa means eight and gon means sides. There are 20 diagonals in an octagon as shown below.

Is octagon straight or curved?

All the sides of an octagon are in a straight-line form. In other words, they are not curved or disjoint with each other. Moreover, every interior angle of a regular polygon will be 135° so the measure of the exterior angle will be 180° – 135° which is 45°.

What does an octagon symbolize?

The octagon and the star octagram were religious symbols for rebirth and resurrection. It was used in baptismal fonts in many churches, large and small. J.C. Cooper states that baptismal fonts were octagonal because the octagon symbolizes renewal, rebirth, regeneration, and transition [1978].

How many triangles does a octagon have?

The picture shows that the octagon is divided into 8 triangles. The sum of the angles in each of the triangles is 180^\circ. So adding up all of the angles of the eight triangles gives 8 \times 180^\circ. All of these angles give the 8 interior angles of the octagon together with the circle around the interior vertex.

What is a real life example of an octagon?

Some examples of octagons are: stop signs. open umbrellas. UFC ring.

Does an octagon have 8 equal sides?

A regular octagon has eight equal sides and eight equal interior angles.
