What is a vertex? for example, there is a triangle with the point of it circled. the book asks if it's a vertex. i looked it up on google and dictionary, but i don't get it. thanks for any help!

1. I found this on Google.

Triangle
The figure formed by three segments joining three noncollinear points. Each of the three points is a vertex of the triangle and the segments are the sides.
