Answer 1

Given, E is the mid point of AD

AB//CD and EF // AB

To prove, F is the mid point of BC

Proof : since AB//CD and EF// AB

Therefore EF // CD

( lines which are parallel to the same line are parallel to one another )

So, E is the mid point of AB

And EF // CD

Therefore F is the mid point of BC [ by converse of mid point theorem]
