Answer:
Option (4). Rhombus
Step-by-step explanation:
From the figure attached,
Distance AB =
=
=
=
Distance BC =
=
=
Distance CD =
=
=
Distance AD =
=
=
Slope of AB () =
=
=
Slope of BC () =
=
If AB and BC are perpendicular then,
But it's not true.
[ = -
]
It shows that the consecutive sides of the quadrilateral are not perpendicular.
Therefore, ABCD is neither square nor a rectangle.
Slope of diagonal BD =
= Not defined (parallel to y-axis)
Slope of diagonal AC =
= 0 [parallel to x-axis]
Therefore, both the diagonals AC and BD will be perpendicular.
And the quadrilateral formed by the given points will be a rhombus.
