Question

name the quadrilaterals in which the following points lie (3,-2) , (-2,-3) ,*,4) and *-2,4)

Answer 1

Answer:

(i) Let the given points are A(−1,−2), B(1,0), C(−1,2)and D(−3,0) Then,

AB=(1+1)2+(0+2)2=22+22=4+4=8

BC=(−1−1)2+(2−0)2=(22+22)=4+4=8

CD=((−3)−(−1))2+(0−2)2=22+(−2)2=4+4=8

DA=(−3)−(−1))2+(0−(−2))2=
