Gɪᴠᴇɴ :-
- PR > PQ.
- PS is Angle Bisector .
Tᴏ SHOW :-
- x > y ?
Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ :-
- If one side of a triangle is longer than another side, then the angle opposite the longer side will be larger than the angle opposite the shorter side.
- An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Sᴏʟᴜᴛɪᴏɴ :-
Given That, PS is Angle Bisector .
So,
→ ∠QPS = ∠RPS = Let z .
And,
Given That, PR > PQ.
So,
→ ∠PQS > ∠PRS . -------- Equation (1).

Now, In ∆PSQ, we have :-
→ ∠PSQ = ∠PRS + ∠RPS ( Exterior angle = sum of Opp. interior Angles).
→ y = ∠PRS + z ---------- Equation (2).

Similarly, in ∆PSR , we have :-
→ ∠PSR = ∠PQS + ∠QPS ( Exterior angle = sum of Opp. interior Angles).
→ x = ∠PQS + z ---------- Equation (3).
___________________
Now, From Equation (1) ,
→ ∠PQS > ∠PRS
Adding z on Both sides we get,
→ ∠PQS + z > ∠PRS + z
Therefore, From Equation (1) & (2) , we get,
→ x > y . (Hence, Proved).

GIVEN:
- PR > PQ
- PS bisects QR
TO PROVE:
- x > y = Angle PSR > Angle PSQ
SOLUTION:
PS is angular bisector so, PR > PQ &
Angle PQS > angle PRS
Assuming as equation 1
_________________
Now, In ∆PSQ, we have :
Using exter angle = sum of two interior opposite angles
→ Angle PSQ = Angle PRS + Angle RPS
→ y = Angle PRS + z
Assuming as Equation (2)
__________________________
Similarly, in ∆PSR, we have :
→ Angle PSR = Angle APS + Angle APS ( Exterior angle = sum of two opposite interior Angles)
→ x = angle PQS+z
Assuming as Equation (3).
__________________________
Now, From Equation (1),
→ Angle PQS > angle PRS
Adding z on Both sides we get,
→ angle PQS + z > angle PRS + z
From equation 1 & 2
We have
x > y
Hence, proved
