Comparing Line Segments AF and ED in a Square: Geometric Analysis

Question

Look at the square below:

Is AF equal to ED?

00:00 Is AF equal to ED?

00:03 We don't know if the lines are parallel to form a parallelogram

00:10 If they were parallel then they would be equal

00:19 We don't have enough data to know

00:22 And this is the solution to the question

Since it is not given that FD is parallel to AE, it cannot be argued that AF is necessarily equal to ED
