Question

I need help understanding this

Answer 1

   I'm assuming that the question's really just asking for the slopes of the straight lines that are both horizontal and vertical, as you wouldn't actually need to graph the rectangle in any way, since you know that a rectangle has two sets of parallel sides with one set of the sides longer than the other. Remember to just use your knowledge of special types of slope to figure this out.

Answer 2

Well, the slope for each side is simple.

All you have to do to remember slope is rise over run.

So for example:
 For Vertices E and F the Slope would be 3/9
For Vertices  G to H the slope would be 3/9
For vertices G to F the slope would be 6/2
For vertices H to E the slope would be 6/2

 
What do you notice about slopes on opposite sides?
Answer:
( H to E,and G to F) Have the same slope
 (And G to H and E to F.) Have the same slope.


What do you notice about slopes of adjacent lines? 
adjacent means adjoining or next to. So can you figure this question out? Using the information above?
