Geometry help please!

Answer 1

@Directrix

Answer 2

The strategy is to do a coordinate Geometry proof and use the slope of a line formula to get the slope of segment DE and then get the slope of segment AB. Parallel lines have equal slopes. So, if you can show that the slopes of these two lines are equal, then you have shown that the lines are parallel.
