Best ResponseYou've already chosen the best response.0There is just really 2 of the parts I don't understand.

Best ResponseYou've already chosen the best response.0I don't understand how to C. and D. After I find the Slope's.

Best ResponseYou've already chosen the best response.1Hmmm, yeah this is interesting. I personally wouldn't prove them to be perpendicular using the method they suggest.

Best ResponseYou've already chosen the best response.1They give you the points, so I would have used the slopes of the diagonals, not the quadrilateral, to prove that their perpendicular to each other.

Best ResponseYou've already chosen the best response.1But I think it's silly to try to use the slope to prove that the diagonals are perpendicular

Best ResponseYou've already chosen the best response.0I would show it for it to be Perpendicular though?

Best ResponseYou've already chosen the best response.1But actually, the slopes are the same for all four sides so that might be a clue as far as the properties of a rhombus go.

Best ResponseYou've already chosen the best response.0So they are all the same?

Hero

Best ResponseYou've already chosen the best response.1Yes, what are the properties of a rhombus? All four sides equal, right?

Hero

Best ResponseYou've already chosen the best response.1If all four sides have the same slope, they must be equal in length. It is not possible for a quadrilateral to have four sides with the same slope and the sides not be equal

Best ResponseYou've already chosen the best response.0So, If it would be Perpendicular would you flip the slope and make it negative?

Hero

Best ResponseYou've already chosen the best response.1If all four sides of a quadrilateral are equal, by definition, it is a rhombus. Therefore, the diagonals will be perpendicular.

Best ResponseYou've already chosen the best response.0So is that my answer for D.?

Best ResponseYou've already chosen the best response.1I admit, it's not a direct proof or anything like that.

Best ResponseYou've already chosen the best response.1You should have asked your instructor what kind of proof he or she wanted

Best ResponseYou've already chosen the best response.0Yeah, I should have. I asked her at the end of the day on Friday and she just said to figure what it would be after you find the slope and perpendicualar.
