Answer:
Option (4) is correct.
Line segment RF lies in between ∠F and ∠R.
Explanation:
Given : A triangle ΔFTR
We have to find the line segment that is included between ∠F and ∠R.
Consider the given triangle ΔFTR
We draw the triangle as shown in attachment below.
Then we can see clearly that Line segment RF lies in between ∠F and ∠R.
Thus, Option (4) is correct.
