graph ABCD...is it a square...A(-3,1) B(1,4)C(4,0)D(0,-3) JUSTIFY YOUR ANSWER AND SHOW WORK..THANK YOU
slope of AB = 3/4
slope of CD = 3/4
slope of BC = -4/3
slope of DA = -4/3
sides are parallel and perpendicular in pairs, so it's a rectangle
|AB|=|CD| = 5
|BC|=|DA| = 5
sides are all equal lengths, so it's a square.
