A circle doesn't have even a single vertex.
In math, a vertex is the point in an angle of which the two rays originate. You know that little dot that's at the "corner" of an angle? Yep, that's the vertex.
The single dot in braille represents 'A'
Use a protractor, or computer software such as GeoGebra (available for free).To draw an an angle of specified measure with a protractor:Draw a straight linePlace a dot at one end of the line. The dot represents the vertex of the angle.Place the center of the protractor at the vertex dot and the baseline of the protractor along line you drew (an arm of the angle).Find the required angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.
a cone
A cone, or an eyedrop.

An angle has two endpoints and a single vertex.
The Lewis Dot form of gold would be the Au (the symbol for gold) with a single dot. The dot represents gold's single valence electron.
