You use the points of the vertex and on the two sides. For example a right angle with a vertex of A and two sides B and C. would be Angle BAC

each side of a angle is a vertex * * * * * No, the point where the sides meet is the vertex. The sides themselves are ... just sides.
the vertex of the angle

It is a straight angle.

It is a vertex.

An angle perhaps
It is a vertex.
It is called the vertex of the angle.
For example, you might name an angle as "ABC", where "B" is the vertex, and "A" and "C" are points lying on the sides of the angle. If there are additional points on the same sides, you can substitute those points instead.
