We equate the two lengths using the length formula for straight lines connecting two points. Since both sides are equal, the square roots can be removed.

A special case is only when D, E and F are all on the same straight line, in which we can use the simpler midpoint formula instead.

For this question, you can't just divide the X and y coordinates of D and E by 2 because the question did not state that F is the midpoint of DE.
