Question

which part of the angle is the vertex?
a. \\(overrightarrow{ab}\\)
b. \\(overrightarrow{ac}\\)
c. point a
d. point c

Explanation:

An angle is formed by two rays with a common endpoint. The vertex of an angle is the common endpoint of the two rays. In the given diagram, the two rays are \(\overrightarrow{AB}\) and \(\overrightarrow{AC}\), and their common endpoint is Point A. Options A and B are the rays themselves, not the vertex. Point C is an endpoint of one ray but not the common endpoint. So the vertex is Point A.

Answer:

C. Point A
