Which set of vertices forms a parallelogram?
A(2,4), B(3, 3), C(6, 4), D(5, 6)
A(1, 1), B(2, 2), C(5, 1), D(4, 1)
A(5, 2), B(3, 3), C(3, 5), D(1, 0)
A(1, 2), B(1, 3), C(5, 3), D(1, 1)

Best ResponseYou've already chosen the best response.0well one thought is to plot them and see which looks like a parallelogram and then find the slopes of the opposite sides to see if they are parallel here is the 1st choice, does it look like a parallelogram

Best ResponseYou've already chosen the best response.0ok... so ignore choice A so then plot the points for B here is option B check the points are correct and decide if its a parallelogram

Best ResponseYou've already chosen the best response.0Okay, so after plotting the points for B, i do think that it is a Parallelogram Am i correct? @campbell_st

Best ResponseYou've already chosen the best response.0U need to test the distance between each two points. When the distance of some opposite pair of sides are equal (I.e for example side 1,3 equal. And side 2,4) If that's true, u can now check the slope of the equal sides, if the slopes r equal, then it' parallelogram. For this question however, I believe the choices can be eliminated by the inequality of the length of opposite sides, which makes the procedure faster

Best ResponseYou've already chosen the best response.0I'm having some problem in sketching from device unfortunately. Anyhow, let's assume I have the points (1,1),(1,1),(1,1)(1,1)

Best ResponseYou've already chosen the best response.0The distqnce between the points (1,1) ,(1,1) equals the distance between (1,1),(1,1),the same holds for the horizontal distance the points parallel to xaxis

Best ResponseYou've already chosen the best response.0Now u can check the slopes of the equal lengths (which r the sides of the parallelogramgram), theymus be parallel, right. Fortunately they are, since the slope lines are equal. Then we proved it's a prallelogram
