Answer: ∠A > ∠ F and ∠L < ∠R
Explanation:
Since, In a triangle if the opposite side of the angle increases then the angle will increases.
That is, the angle that have the greatest opposite side is the greatest angle of triangle.
Here In triangle ABC and DEF,
BC > DE ( by the given diagram)
Where BC and DE are the opposite sides of angle of ∠A and ∠F respectively.
Therefore, ∠A > ∠ F
Now, In triangles RST and LMP,
ST > MP ( by the given diagram)
where ST and MP are the opposite sides of angles R and L respectively.
Therefore, ∠ R > ∠L
