उत्तर

Join A to P. 

In Δ AMPand Δ DMP 

MP = MP 

AM = MD 

∠ AMP = ∠ DMP = 90° 

Therefore, Δ AMPand Δ DMP are congruent. 

DP= AP ....... (i) 

In Δ ANP and Δ BNP 

NP= NP 

AN= NB 

∠ANP = ∠BNP = 90° 

Therefore, Δ ANP and Δ BNP are congruent. 

BP= AP ....... (ii) 

From (i) and (ii) 

BP= DP 

Hence, proved.
