I wish you could have been my teacher in middle school. You're awesome Sal

Sal, I came up with a very simple solution: 5*360-3*180-5*180=360 5*360 --- all five full angels 3*180 --- (n-2)*180 - all 5 internal angles 5*180 --- 5 adjacent external angles. So a general rule would be: n*360-(n-2)*180-n*180=360 Q.E.D. If you find useful you can make a video on it :) KHANACADEMY - best school on Earth.

You're great at explaining things! So easy to understand. Thanks!

@smicha7 It's easier for me to just remember that a convex polygon's outer angles will total 360°.

This was so helpful! Thank you! :D

Thank you so much! This cleared my concept :) Btw anyone got this assignment from online school? :' (I got a test which includes this T_T)

Yeah basically

May I know the software and hardware that you use to draw the diagrams in your video?

[@nirmalakale479]

Sir you videos are nice

[@WSCOMPUTER]

@thisshouldsay2K You are right, but I meant a proof, not something to remember.

[@brennan2185]

I am having the same problem I have done dozens and dozens of problems and the answers seem to be rather arbitrary. It doesn't stick to the formula(s) that is provided.

[@karmaakabane2165]

So this guys just knows everything huh

[@Basic719]

So it's not applicable for concave polygon ??

[@fightforfitness2256]

You helped me a lot, thanksssssssssssssssss................

[@ajitkumar-mu8bp]

it has three lines coming out from one point

@smicha7 Ah. Well yeah, then that will work.

THANKS

loVE UR USERNAME

[@JohnnyLion66]

But Sal, NONE of the polygon in the "Angles of a Polygon" exercise don't seem to be concave. And some of the polygons used in the exerciise don't look anything like a 360 degree polygon, but the answer to the problem on just about every other problem is 360 degrees. So, how do I know when to apply this "elegant" way?
