Hi!

'The length of any side of a triangle must smaller than the sum of the other two sides.

The same for pentagon: the length of any side of a pentagon must be smaller than the sum of the other four sides.'

Does this apply to all polygons?


RTN

It appears to be the case.

Yes, the video explains why this holds for any closed figure. Thanks achloes for sharing it.
