How many sides do a hexagon have?
six sides
A hexagon is a 2D geometric polygon that has six sides and six angles. It has no curved sides and all the lines are closed. The internal angles of a regular hexagon add up to 720 degrees.
How many corners does an octagon have?
eight vertices
An octagon has eight straight sides and eight vertices (corners). It has eight angles inside it that add up to 1080°.
Are all 8 sides of an octagon equal?
The octagon having eight congruent sides and angles is known as a regular octagon. In a regular octagon, all the sides are equal in length, and all the angles are equal in measure. The interior angles add up to 1080° and the exterior angles add up to 360°. The interior angle at each vertex of a regular octagon is 135°.

| Heptagon | 7 |
| Octagon | 8 |
What is an 8 sided shape called?
octagon
An octagon is a shape with 8 sides and 8 angles.
How many sides has Pentagon?
five sides
| 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) |
How many sides are there in Decagon?
10
Decagon/Number of edges
How many triangles are in an octagon?
Divide the octagon into 8 triangles. Each triangle has 2 sides of equal length.
What are angles of octagon?
An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees. Because the octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8.
How many sides is 7?

What angle do you cut wood to make an octagon?
360 degrees in a circle divided by 8 for your octagon is a 45 degree angle divided by 2 for your mitre cut is 22.5″ on your saw. doesn’t matter if its a 2″ circle or a 22″ circle. you just need to determine the length of your parts.
How many vertices does an octagon have?
Looking at the above figure we see that an octagon comprises 8 sides and eight vertices. This makes it a regular octagon as the angles and sides are all equal. Similarly, we have other kinds of polygons that divide on the basis of the sides and angles.
How many edges does an octagon Prism have?
The octagonal prism is a 3D uniform polyhedron bounded by 2 octagonal faces and 8 squares. It has 24 edges and 16 vertices. It may be considered to be the extrusion of the octagon.
What is the sum of the angles of an octagon?
So, the sum of the interior angles of an octagon is 1080 degrees. So, the measure of the central angle of a regular octagon is 45 degrees.
