# Is an octagon a regular polygon Why or why not?

## Is an octagon a regular polygon Why or why not?

A regular octagon has eight congruent angles and eight congruent sides. Any polygon that does not have all congruent sides is an irregular polygon. Irregular polygons can still be pentagons, hexagons and nonagons, but they do not have congruent angles or equal sides. Here are some examples of irregular polygons.

Is a octagon A polygon yes or no?

Why is it called a polygon?

The word polygon comes from the Greeks, like most terms in geometry, which they invented. It simply means many (poly) angles (gon). A polygon can’t have any curves or any gaps or openings in its shape.

### Why is an octagon not regular?

In other words, an irregular Octagon has eight unequal sides and eight unequal angles. It is an octagon with unequal sides and angles. All the interior angles are of different measure, but their sum is always 1080º.

Is octagon a regular polygon?

The regular octagon is the regular polygon with eight sides, as illustrated above.

Is an octagon a convex polygon?

The octagon, which has all its angles pointing outside and no angle pointing inwards, is convex. Each angle of a convex octagon is less than 180°.

## Does a octagon have 8 vertices?

An octagon can be defined as a polygon having eight sides, eight interior angles, and eight vertices. When all the sides and angles of an octagon are equal in measurement, it is called a regular octagon.

Is octagon a convex polygon?

Is a hexagon a regular polygon or not a regular polygon?

Yes, a hexagon is a polygon.Polygon is having n no of sides.Whenever polygon is having 6 sides, then it is called as hexagon.

### Is an octagon an irregular shape?

An octagon is an eight-sided shape, such as a stop sign. Octagons can be regular or irregular. A regular octagon has sides that are congruent, or all equal. An irregular octagon has sides with different lengths.

Is an octagon regular or an irregular shape?

Like other polygons, an octagon can be classified as regular or irregular. If all the sides and interior angles of an octagon are equal, it is a regular octagon. Otherwise it is an irregular octagon. Octagons and other polygons can also be classified as either convex or concave.

What is the difference between Polygon and Octagon?

As nouns the difference between polygon and octagon is that polygon is (geometry) a plane figure bounded by straight edges while octagon is (geometry) a polygon with eight sides and eight angles.
