The coordinates of the vertices of quadrilateral ABCD are A(−6, 3) , B(−1, 5) , C(3, 1) , and D(−2, −2) . Which statement correctly describes whether quadrilateral ABCD is a rhombus?
A. Quadrilateral ABCD is not a rhombus because opposite sides are parallel but the four sides do not all have the same length.
B. Quadrilateral ABCD is a rhombus because opposite sides are parallel and all four sides have the same length.
C. Quadrilateral ABCD is not a rhombus because there are no pairs of parallel sides.
D. Quadrilateral ABCD is not a rhombus because there is only one pair of opposite sides that are parallel.

Answer:

Option C is correct.

Explanation:

Rhombus states that a parallelogram with four equal sides and sometimes one with no right angle.

Given: The coordinate of the vertices of quadrilateral ABCD are A(−6, 3) , B(−1, 5) , C(3, 1) , and D(−2, −2) .

The condition for the segment [tex](x_{1},y_{1})[/tex], [tex](x_{2},y_{2})[/tex] to be parallel to [tex](x_{3},y_{3})[/tex],  [tex](x_{4},y_{4})[/tex] is matching slopes;

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}= \frac{y_{4}-y_{3}}{x_{4}-x_{3}}[/tex] or

[tex](y_{2}-y_{1}) \cdot (x_{4}-x_{3}) =(y_{4}-y_{3}) \cdot (x_{2}-x_{1})[/tex]     ....[1]

So, we have to check that [tex]AB || CD[/tex] and [tex]AD || BC[/tex]

First check [tex]AB || CD[/tex]

A(−6, 3) , B(−1, 5) , C(3, 1) , and D(−2, −2)

substitute in [1],

[tex](5-3) \cdot (-2-3) = (-2-1) \cdot (-1-(-6))[/tex]

[tex]2 \cdot -5 = -3 \cdot 5[/tex]

-10 ≠ -15

Similarly,

check [tex]AD || BC[/tex]

A(−6, 3) , D(−2, −2) , B(−1, 5) and C(3, 1)

Substitute in [1], we have

[tex](-2-3) \cdot (3-(-1)) = (1-5) \cdot (-2-(-6))[/tex]

[tex]-5 \cdot 4 = -4 \cdot 4[/tex]

-20 ≠ -16.

Both pairs of sides are not parallel,

therefore, Quadrilateral ABCD is not a rhombus because there are no pairs of parallel sides.
