Question

1. in \\( \triangle ftr \\), which side is included between \\( \angle r \\) and \\( \angle f \\)?

\\( \overline { r f } \\)
\\( \overline { r t } \\)
\\( \overline { t f } \\)
\\( \overline { f t } \\)

Explanation:

Step1: Recall the definition of included side

The included side between two angles in a triangle is the side that has both angles as its endpoints.

Step2: Identify the endpoints of the side between ∠R and ∠F

In triangle \( \triangle FTR\), the side with endpoints \(R\) and \(F\) is \( \overline{RF}\).

Answer:

\(\overline{RF}\)
