Question

one way this angle can be named is: ∠abc ∠acb ∠bca ∠cab

Explanation:

Step1: Recall angle - naming rules

An angle can be named using three points, with the vertex in the middle.

Step2: Identify the vertex

In the given angle, the vertex is point \(B\).

Step3: Apply the naming rule

Using the three - point naming method (\(\angle\) followed by the three points with the vertex in the middle), for points \(A\), \(B\), and \(C\) (where \(B\) is the vertex), the angle is named \(\angle ABC\).

Answer:

A. $\angle ABC$
