To Prove :-
Construction :-
Draw PS parallel to BR to meet AC at S.
Proof :-
In Δ BCR, P is the mid-point of BC and PS is parallel to BR.
Where, S is the mid-point of CR
So, ----- (1)
Again, In Δ APS, Q is the mid-point of AP and QR is parallel to PS.
Where, R is the mid-point of AS.
So, ----- (2)
From equations (1) and (2),
We get, AR = RS = SC
