If you're interested in such a use, we recommend the flooring calculator and the square footage calculator as they are very good tools for this purpose. The next case is common to all polygons, but it is still interesting to see. In photography, the opening of the sensor almost always has a polygonal shape.
This part of the camera called the aperture , and dictates many properties and features of the pictures taken by the camera. The most unexpected one is the shape of very bright point-like objects due to the effect called diffraction grating , and it is illustrated in the picture above.
One of the most important uses of hexagons in the modern era, closely related to the one we've talked about in photography, is in astronomy. One of the biggest problems we experience when trying to observe distant stars is how faint they are in the night sky. That is because despite being very bright objects, they are so very far away that only a tiny fraction of their light reaches us; you can learn more about that in our luminosity calculator. On top of that, due to relativistic effects similar to time dilation and length contraction , their light arrives on the Earth with less energy than it was emitted.
This effect is called the red shift. The result is that we get a tiny amount of energy with a bigger wavelength than we would like. The best way to counteract this, is to build telescopes as big as possible. The problem is that making a one-piece lens or mirror bigger than a couple meters is almost impossible, not to talk about the issues with logistics. The solution is to build a modular mirror using hexagonal tiles like the ones you can see in the pictures above.
Making such a big mirrors improves the angular resolution of the telescope as well as the magnification factor due to the geometrical properties of a "Cassegrain telescope". So we can say that thanks to regular hexagons we can see better, further and more clearly than we could have ever done with only one-piece lenses or mirrors.
Did you know that hexagon quilts are also a thing?? The honeycomb pattern is composed of regular hexagons arranged side by side. They completely fill the entire surface they span, so there aren't any holes in between them. This honeycomb pattern appears not only in honeycombs surprise!
In fact, it is so popular that one could say it is the default shape when conflicting forces are at play, and spheres are not possible due to the nature of the problem. From bee 'hives' to rock cracks through organic chemistry even in the build blocks of life: proteins , regular hexagons is the most common polygonal shape that exists in nature.
And there is a reason for that: the hexagon angles. For the full description of the importance and advantages of regular hexagons, we recommend watching the video above. To those who are hard-core readers, read on you can check how fast you read with the reading speed calculator.
This is a significant advantage that hexagons have. Another important property of regular hexagons is that they can fill a surface with no gaps in between them along with regular triangles and squares. On top of that, the regular 6-sided shape has the smallest perimeter for the biggest area amongst these surface-filling polygons, which obviously makes it very efficient.
A very interesting example in the video above is that of the soap bubbles. When you create a bubble using water, soap and some of your own breath, it always has a spherical shape.
This is because the volume of a sphere is the largest of any other object for a given surface area. However, when we lay the bubbles together on a flat surface, the sphere loses its efficiency advantage , since the section of a sphere cannot completely cover a 2D space.
The next best shape in terms of volume to surface area happens to also be the best at balancing the inter-bubble tension that is created on the surface of the bubbles. We are, of course, talking of our almighty hexagon. Bubbles present an interesting way of visualising the benefits of a hexagon over other shapes, but is not the only way. In nature, as we have mentioned, there are plenty of example of hexagonal formations , mostly due to stress and tensions in the material.
We cannot go over all of them in detail, unfortunately. We can, however, name a few places where one can find regular hexagonal patterns in nature:.

How many sides does a hexagon have? Exploring the 6-sided shape It should come as no surprise that the hexagon also known as the "6-sided polygon" has precisely six sides. Hexagon definition, what is a hexagon? Hexagon area formula: how to find the area of a hexagon We will now have a look at how to find the area of a hexagon using different tricks.
Diagonals of a hexagon The total number of hexagon's diagonals is equal to 9 - three of these are long diagonals that cross the central point, and the other six are the so called "height" of the hexagon. Here is how you calculate the two types of diagonals: Long diagonals - they always cross the central point of the hexagon.
Circumradius and inradius Another pair of values that are important in a hexagon are the circumradius and the inradius. Circumradius : to find the radius of a circle circumscribed on the regular hexagon, you need to determine the distance between the central point of the hexagon that is also the center of the circle and any of the vertices. How to draw a hexagon shape Now we are going to explore a more practical and less mathematical world: how to draw a hexagon.
The easiest way to find a hexagon side, area We have discussed all the parameters of the calculator, but for the sake of clarity and completeness we will now go over them briefly: Area : 2-D surface enclosed by the hexagon shape, Side Length : Distance from one vertex to the next consecutive one, Perimeter : Sum of the lengths of all hexagon sides, Long Diagonal : Distance from one vertex to the opposite one, Short Diagonal : Distance between two vertices that have another vertex between them, Circumcircle radius : Distance from the centre to a vertex Same as the radius of the hexagon , Incircle radius : Same as the apothem.
Hexagon tiles and real-world uses of the 6-sided polygon Everyone loves a good real-world application , and hexagons are definitely one of the most used polygons in the world.
Honeycomb pattern - why the 6-sided shape is so prevalent in nature The honeycomb pattern is composed of regular hexagons arranged side by side.

It is a 6-sided polygon with two types - regular hexagon and irregular hexagon. A hexagon is a two-dimensional shape having 6 sides.
It may be equal or unequal. Therefore, all six-sided closed shapes are hexagons. Hexagon may not necessarily have all sides equal. It can have sides of variable lengths too. The hexagon having equal sides is called a regular hexagon and the one with different sides is called an irregular hexagon. A hexagon is classified based on the side lengths and angles.
Based on this, hexagons are classified into regular equal side-lengths and angles and irregular unequal side-lengths and angles hexagons. Since a hexagon has 6 sides, taking 'n' as 6 we get. A hexagon has 6 sides. For all regular polygons, the number of lines of symmetry is equal to the number of sides. Thus, for a regular hexagon, there are six lines of symmetry. We can determine the area of a hexagon by i dentifying the length of the side of the hexagon.
Always write the final answer of area in square units. The formula to calculate the regular hexagon perimeter is 6a units, where 'a' is the side length of the hexagon. In the case of an irregular hexagon, we add the side lengths. Learn Practice Download. Hexagon A hexagon is a closed 2D shape that is made up of straight lines.
