Answer this ques.
Dear Student,
Given - In triangle ABC, D is the midpoint of BC and DQ are drawn parallel to BA.
To Prove - FD=1/3FE
Proof - In triangle ABC, D is the midpoint of BC and DQ are drawn parallel to BA.
therefore, Q is the mid-point of AC.
AQ = QC
Now, FA DQ PC and AQC is transversal such that AQ = QC and FDP is the another transversal on them.
FD = DP .........(i) [by intercept theorem]
EC= (1/2) AC = Qc
in tr. EQD,
C is the midpoint of EQ and CP DQ.
P must be the midpoint of DE.
DP = PE.....(ii)
thus, FD = DP = PE [from (i) and (ii)]
hence, FD = (1/3) FE.
Please ask the next part in different thread.
