Hi Emma:
The answer is True.
Here's why: the distance formula L = √ [(x1 - x2)2 + (y1 - y2)2 ] is derived from Pythagoras since for any 2 points (x1, y1) and (x2, y2), we can always draw a right triangle with horizontal base = (x1 - x2) and vertical side = (y1 - y2).
The, by Pythagoras, the square of the distance between them is (x1 - x2)2 + (y1 - y2)2
and the distance between them is √ [(x1 - x2)2 + (y1 - y2)2]
