What shape has 20 sides?

Okay, let’s play a game. I will describe a shape, and you have to guess what shape it is. Ready? Here we go:
– It has twenty sides.
– Each side is of equal length.

Got an answer for me?

If you guessed that the shape which has twenty sides is an icosagon, then congratulations! You are smarter than most people in the world who don’t even know that such a thing exists!

Now, only because you managed to impress us with your geometry knowledge, let’s give you some more details about this rare specimen of polygons.

What Is An Icosagon And How Rare It Is

The icosagon is basically a regular polygon with twenty sides and twenty angles (Also known as angles between two adjacent lines). In math terms, it can be represented by {20}, where ‘n’ stands for the number of edges or vertices (corners)of the polygon. So always remember kiddos; if someone throws {20} at you during math class next time and asks what it represents – point proudly to your brain.

But now here comes the really interesting part – when was the last time anyone used words like “Icosagon” in their daily lives anyway? Never actually!

An icosacontakaihenagon might sound hilarious too but sadly they do not exist anywhere except in our mathematical curriculums hence making them both annoyingly nerdy and dull. We mean who cares how many ‘k’ an “Icosacontakaihenaon” ends up having?
Don’t bother counting..it’s 61 by-the-way(told ya!).

So congrats on finally putting your complex maths lesson into use somewhere apart from classroom tests perhaps?

The Properties Of An Icosagon

Of course there would definitely be several questions swirling around one’s mind when things start getting unnecessarily increasingly complex. The next question is how to figure out what all comes inside a polygon? Well, let’s put our smarty pants back on and break it down:

Side Length

Just like any other regular polygon (a symmetrical closed shape with sides of the same length), all twenty edges – also referred to as ‘sides’- of an icosagon are equivalent.
For instance: Take any one stick or pencil if you will, make tiny marks at equal intervals, keeping up the rhythm till successfully plotting 20 dots uniformly across it then connect them through lines.. Voilà! Pat yourself on back for producing an icosa-fyi-an 😁

Interior Angles

The interior angle is defined as the angle formed by two adjacent sides when measured between those two sides. To calculate this,the total degrees that make up these angles can be found using a simple formula:
(n-2) x 180 degrees/ n where ‘n’ stands for number of vertices in your given polygon.

The final value then needs to be divided by however many angles there are i.e (n). Giving us measurement of individual internal angles. For icosagons specs that could work out as :
(20 -2) x 180 /20 which = ~162 degrees So now we know each corner points towards approximately roughly One hundred sixty-two degree mark contributing towards what makes this bizarre looking creature.

It’s easy right? Wrong! Who knew polygons required so much critical thinking either ways!

Practical Use Of Icosagons

Don’t gimme that look,you might occassionally end up being asked about them who knows . But frankly speaking apart from “Math Freaks” and architects,I doubt majority may ever come face to face with their nefarious properties except maybe spotting shapes representing side views or plans occasionally in buildings and airports perhaps?

Conclusion

Well friends,it still boggles the mind why math teachers all over may be keen to teach about something that remains practically irrelevant for most of our lives. Nonetheless we are sure you have learned so much today and now could acr up there as a hero amongst your peers-which is all that matters in some capacity at least 😉

So, next time when someone asks you “what shape has twenty sides?”you can hit back with certainty“ it’s an Icosagon, duh”.

Until then let’s stick to good old shapes like triangles or circles! Talking about circles though…(we’ll reserve for another day haha).
