What is the most precise term for quadrilateral ABCD with vertices A(3,1) , B(4,5) , C(7,5) , D(7,2) answer choices; A. KITE B.
SOVA2 [1]

Answer:

Step-by-step explanation:

Given are the vertices of a quadrilateral.

WE have to find the name of the quadrilateral

WE have slope of AC = (5-1)/(7-3) = 1

and slope of BD = (2-5)/(7-4) = -1

Since m1m2 =-1 we get

the diagonals cut at right angles

This property is special property for square, rhombus and kite only.

Let us check if diagonals bisect each other

Mid point of AC = (\frac{3+7}{2} ,\frac{1+5}{2} =(5,3)

Mid point of BD =(\frac{4+7}{2} ,\frac{2+5}{2} =\neq 5,3)

Since diagonals do not bisect this is neither rhombus nor square.

Only possibility is kite
