Yeah, and a regular triangle is actually a 4-sided figure where 3 vertices lie on the same line. :D:D:D
But okay, let's say this is an incorrect option (something also confuses me in it, but not the vertices lying on the same line). I'll find another one.
Especially for people like you, I will rephrase the question.
In city N (the shape doesn't matter), there is a "ring" road consisting of 111 straight sections that do not intersect each other. A straight highway runs through the city. Is it possible for a car traveling along the highway through the city to cross all 111 sections of the "ring" road?
