Additionally, is any 8 sided shape an octagon? An 8sided shape is called an octagon. Any time that a shape is a polygon, and it has eight sides, we call it an octagon.

Simply so, do octagons have to have equal sides?

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

What is the definition of a regular octagon?

Regular octagons have sides that are congruent. They also have congruent angles, which means that the measurement of all of the angles is the same, too. The exterior angles of a regular octagon are all 135 degrees and the interior angles are all 45 degrees.

### Is there a shape with 10 sides?

A decagon is a 10-sided polygon. It also has ten vertices – which is where the sides meet – and ten angles.

### Can octagons look different?

Irregular octagons are a little more difficult to spot because although they will have eight sides and eight angles, those sides may not be equal, and so the angles may be very different. They may look pretty unusual, but count the sides and you’ll know. If it’s an octagon, it will have eight sides.

### What is shaped like a pentagon?

A polygon is a plane (2 dimensional) figure that features at least 3 straight sides and angles. Regular pentagons have sides of equal length and interior angles of 108 degrees. The US Department of Defense headquarters is named ‘the Pentagon’ . The edible plant okra is shaped like a pentagon.

### What is a polygon shape?

Definition of a Polygon A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.

### Where can you find a Pentagon in real life?

There are examples of pentagons in real life in man-made structures like the Pentagon in the United States, and also in nature in flowers like morning glories and okra. Other items, like home plates in baseball, are often in the shape of irregular pentagons. A pentagon is a five-sided shape.

### What is an example of a hexagon?

The definition of a hexagon is a figure with six sides. A stop sign with six sides is an example of a hexagon.

### What does a rhombus look like?

A rhombus looks like a diamond Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram). And the diagonals “p” and “q” of a rhombus bisect each other at right angles.

### What does a trapezoid look like?

A trapezoid is a four-sided flat shape with one pair of opposite parallel sides. It looks like a triangle that had its top sliced off parallel to the bottom. Usually, the trapezoid will be sitting with the longest side down, and you will have two sloping sides for the edges.

### What is a 3 sided shape called?

A 3-sided shape is called a triangle. Triangles are polygons with three sides, so any polygon with three sides is called a triangle.

### What is a 9 sided shape called?

Nonagon. In geometry, a nonagon (/ˈn?n?g?n/) or enneagon (/ˈ?ni?g?n/) is a nine-sided polygon or 9-gon.

### Is a circle a polygon?

Polygons. A polygon is a closed plane figure with three or more sides that are all straight. The following figure is not a polygon as it is not a closed figure. A circle is not a polygon as it does not have straight sides.

### Can an octagon have 6 right angles?

So an octagon can have 6 right angles. Sum of angles = 1260′. For a polygon with n sides, sum of interior angles = 180n – 360 degrees.

### What is a 6 sided shape called?

In geometry, a hexagon (from Greek ?ξ hex, “six” and γωνία, gonía, “corner, angle”) is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.

### How many sides does a regular polygon have?

You know that each of the interior angles is 165 degrees so that gives you half of your equation, 165 times n, or 165n. Second, set your interior angles equal to the interior angle formula (n-2)180 = 165n. Last, solve for n. Divide by 15 to get n = 24 sides to the polygon.
