### Do octagons have equal sides?

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

**How many angles do octagons have?**

8 angles

An octagon consists of 8 angles. The sum of the angles of an octagon is 1080°.

## What does a nonagon look like?

A regular nonagon is a nine-sided shape with equal sides and equal angles of 140 degrees each. Each interior angle measure of a regular nonagon is 140 degrees.

**Are all octagons similar?**

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)… And there are eight angles… So, the measure of the interior angle of a regular octagon is 135 degrees.

**What is a Heptagon shape?**

In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon.

## Are all regular N-Gons similar?

In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star….Regular polygon.

**How many sides does an octagon have?**

Also, based on the length of these sides, octagons are classified as regular and irregular octagons. As defined above, the octagonal shape contains 8 angles at 8 vertices. Thus, the octagon holds 8 sides and 8 angles. There are 8 interior angles and 8 exterior angles in an octagon. Octagon interior angles sum is equal to 1080 degrees.

### What is a shape with 8 sides?

Jump to navigation Jump to search. shape with eight sides. 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.

**What is the name of the 8-sided polygon?**

Octagon. An octagon is an 8-sided polygon (a flat shape with straight sides). First, have a play with an octagon: Regular or Irregular. When all angles are equal and all sides are equal it is regular, otherwise it is irregular

## How do you know if an octagon is regular or irregular?

If all the sides and angles of an octagon are of the same measure, then it is called the regular octagon. If the octagon has unequal side length and angle, then it is called an irregular octagon. Define convex and concave octagon.
