Question

explain the answer
if I got correct answer I swear I will give ten thanks and I mark u as brainlist​

Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

pls refer the reference diagram uploaded above as there is some construction work in original diagram

Step-by-step explanation:

so here in trapezium abcd

ab parallel to dc (given)

also ef parallel to ab (given)

thus then ab parallel to dc parallel to ef by transitivity postulate

now considering triangle ADC

as ab ef ie eo parallel to dc

by basic proportionality theorem

we get

AE/ED=AO/OC (1)

now considering triangle abc

as ef ie of parallel to ab

Again using bpt

we get

AO/OC=BF/FC (2)

thus then

AE/ED=BF/FC from (1) and (2)

now applying alternendo

we get

AE/BF=ED/FC

so here AE/BF=2

hence then also

ED/FC=2

if u have any doubt in geometry or statistics do ask me they are my life

I just can't live without these two in maths
