The points \[(1,1),\,(-1,5),\,(7,9)\] and \[(9,5)\] taken in such order that it will form a
A) Rectangle
B) Square
C) Rhombus
D) None of these
Correct Answer:
A
Solution :
Let the points be \[A(1,1),\,B(-1,5),\,C(7,9)\]and \[D(9,5)\] Now, by using distance formula, we get Hence, AB = CD and BC = DA and AC = BD \[\therefore \] ABCD forms a rectangle.
