Question

select the correct answers. if an angle is represented with three letters a, b, and c and a is the vertex of the two rays, which of the following are the angles names.
a ∠bac
b ∠a
c ∠b
d ∠c
e ∠cab
f ∠bca

Explanation:

When naming an angle with three letters, the vertex (in this case \(a\)) is in the middle. So \(∠bac\) and \(∠cab\) are incorrect as the vertex is not in the middle. When naming an angle with one letter, the letter represents the vertex. So \(∠a\) is correct.

Answer:

B. \(∠a\)
