Fill in the blanks!
in triangle abc shown below, point a is at (0, 0), point b is at (x2, 0), point c is at (x1, y1), point d is at (x1 over 2, y1 over 2), and point e is at (x1 + x2 over 2, y1 over 2)
prove that segment de is parallel to segment ab

by applying the formula, i find that the slope of segment de is since the difference between the y-coordinates if points d and e is and any number divided into 0 is the slope of segment ab is also because (0 - 0)/(x2 - 0) = because the two segments have the same they must be parallel according to the definition of
