Question

b. in △stu, which angles include $overline{us}$?
∠s and ∠t
∠t and ∠s
∠t and ∠u
∠s and ∠u

Explanation:

Step1: Recall angle - side relationship in a triangle

In a triangle, an angle is said to include a side if the side is between the two rays that form the angle. In \(\triangle STU\), the side \(\overline{US}\) has endpoints \(U\) and \(S\). The angles with vertices at the endpoints of the side \(\overline{US}\) are \(\angle U\) and \(\angle S\).

Answer:

\(\angle S\) and \(\angle U\)
