Number of Diagonals In a Regular Polygon - Geometry

This geometry video tutorial explains how to calculate the number of diagonals in a regular polygon such as a square, pentagon, hexagon, heptagon, and an octagon. It also explains how to confirm the answer by drawing the diagonals in a regular polygon. In addition, it discusses how to determine the type of polygon given the number of diagonals as well as the sum of the interior angles of a polygon and the measure of each interior angle and exterior angle.

Thank you so much this helped me alot in my math test!!! Hope that you stay safe in these strange times😷

[@georgesadler7830]

Mr. Organic Chemistry Tutor, thank you for another incredible video/lecture on the Number of Diagonals In a Regular Polygon. From the different shapes in Plane/Solid Geometry, it's really good to know how to calculate the diagonals of each shape and also the interior/exterior angles.

Why do you use 3 in the formula for the heptagon? I get it arrives at the correct answer...but why do you use 3 instead of 4?

[@Holloworld99]

Look I’m diving into to this blind too and I just want to understand it to I guess the number 3 is a universal number for these equations

[@shashikantyadav8000]

You are great Organic Chemistry Teacher

[@welcom9127]

What is the use of this formula in future?

[@tristisludos]

This could be used in architecture if you ever need support beams in an irregular polygon, as the number of diagonals aren't always apparent.

Thank u po🙏😇

you should show n= -5 error because 14 70 devides by 5 2 and 7 so how did you get thw7 and the 10

I'm not the kind of person to comment on videos, but I would like to give my full, genuine appreciation to you, Sir! I was able to answer our quiz retake because of this video. I just hope our professor will still accept my answer. Nevertheless, I was able to learn from this. Thank you so much!🫡🫡🫡
