Question

which angle number represents an angle vertical to ∠bgc? answer attempt 2 out of 2

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other.

Step2: Identify intersecting lines

Lines \(AB\) and \(CD\) intersect at point \(G\). \(\angle BGC\) and \(\angle AGD\) are vertical angles. In terms of the numbered angles, \(\angle BGC\) is angle \(1\) and the vertical - angle to it is angle \(2\).

Answer:

\(2\)
