Question

He given figure , pq is parallel to ba and pr is parallel to ca.. if pd =12cm ,find bd *cd

Answer 1

PQ II BA (Given)
⇒ PQ II BR
Now, in Δ BDR,
PQ II BR
By BPT 
PD/BD = DQ/DR ....(1)
PR II CA (Given)
⇒ PR II CQ
Now,
IN Δ PRD
PR II CQ
BY BPT
CD/PD = DQ/DR .....(2)
From (1) and (2), we get
PD/BD = CD/PD
⇒ BD × CD = (PD)²
BD × CD = (12)²
BD × CD = 144 cm answer.
