Basic Graph Theory I - vertices, edges, loops, and equivalent graphs

This video goes over the most basic graph theory concepts. We cover vertices, edges, loops, and equivalent graphs, along with going over some common misconceptions about graph theory.

Ma'am
This is much better explanation than even my 📕

Can a graph with only 1 vertex with 2loops be considered as connected graph?

[@wataripg]

I'm hoping you might be able to help me with something. I am wondering why the terms "vertices" and "edges" were used for what more properly seem to be "nodes" and "links". A vertex by definition is a point where _two_ or more lines meet to form an angle (like the vertices of a polygon). However, some of the "vertices" in the graphs you've described are isolated, having only one line linked to them. How is this a vertex? Again, "node" seems like a much better and more acurate term. Also, I am confused about the term "edges". What makes it an edge (the outer or farthest point of something)? Again, "link" seems like a much better and more acurate term. I am sure there must be some reason why these terms were chosen. They have cropped up in other articles and texts I've read too. It seems to be the common parlance in graph theory, but why those terms, and what gave rise to them? Would appreciate whatever insight you might be able to offer.

I guess Im asking randomly but does any of you know of a way to get back into an Instagram account..?
I stupidly forgot my account password. I love any help you can give me.

@Magnus Barrett instablaster ;)

[@magnusbarrett9575]

@Theo Richard thanks so much for your reply. I found the site on google and im in the hacking process atm.
I see it takes quite some time so I will reply here later with my results.

[@magnusbarrett9575]

@Theo Richard It did the trick and I actually got access to my account again. Im so happy!
Thanks so much you saved my account!

@Magnus Barrett glad I could help :D

WHAT IS WEIGHT IN GRAPHS

[@michaelastone7839]

Weight is when a value (number) is assigned to each edge of the graph. To find the weight of a path, you would add up the values of all of the edges used in the path.
