Question

Using the drawing, what's the vertex of angle 4

Answer 1

Using the four points around the drawing, we can see that angle four is connected to the vertex A.

The answer I believe is:
D. Vertex A.

Hope I could help! Have a good one.

Answer 2

(D) A is the correct answer.

Explanation:

A vertex is commonly known as the intersection of two sides of a plane figure and also The point about which an angle is measured is called the angle's vertex, and any angle associated with a given vertex is called the vertex angle.

since, the angle 4 is associated with a given vertex A,

Thus, the vertex of the angle 4 is "A".

Hence, option D is correct.
