⭐Here is your answer⭐
⭐ Given:- ABC is a ∆.
Construction:- Join B to K. Such that AB= BK
Prove that:- Angle B > Angle C.
Proof:-
⭐⭐In ∆ ABK,
⭐⭐AB = BK ( Construction)
⭐⭐Angle 1= Angle 2
⭐⭐ Angle 1 > Angle C
So that,
⭐⭐Angle ABK > Angle 1 ( The whole is greater than the part.)
Then,
⭐⭐Angle ABK > Angle 2 ( Angle 1= Angle 2) eq-1
⭐⭐Angle 2 > Angle C eq-2
⭐⭐Now, Combining both the equation:-
⭐⭐Angle ABK > Angle 2
⭐⭐Angle 2 > Angle C
⭐⭐(Angle 2 will be Cancelled)
⭐⭐Angle ABK > Angle C
⭐⭐or Angle B > Angle C
⭐⭐Hence, AC is a longer side and Angle B is larger angle.
Proved.
