Answer:
AB has a slope of 6-1/ -4 - (-4) = 5/0 which is undefined because there is a zero at the bottom.
BC has a slope of 4-6/2- (-4)= -2/6
CD has a slope of 3-4/ 2-2= -1/0 which is also undefined
AD has a slope of 3-1/ 2- -(4) = 2/6
THERE is 1 pair of parallel sides so the shape is indeed a trapezoid
BC= [tex]\sqrt2-(-4)^2 +(4-6)^2 = \sqrt36+4 = \sqrt40[/tex]
AD= [tex]\sqrt2-(-4)^2 + (3-1)^2 = \sqrt36+4 = \sqrt40[/tex]
They are equal in length which means the trapezoid is isosceles
