If A(1, 1), B(5, 4), C(10, 3), and D(6, 0) are the vertices of a quadrilateral, do the points form a parallelogram? Justify your answer.

Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals negative start fraction three over four end fraction comma and AD = BC = 5 units.
Yes, it is a parallelogram because the slope of segment AB equals the slope of segment DC, which equals start fraction three over four end fraction comma and AB = CD = 5 units.
Yes, it is a parallelogram because the midpoint of the diagonals segment AC and segment BD is (5.5, 2).
No, it is not a parallelogram because the slope of segment AB = 1 and the slope of segment DC equals negative start fraction three over four end fraction full stop

Respuesta :

I believe the answer is yes, it is a parallelogram because the slope of segment AB equals to the slope of segment DC, which equals start fraction three over four end fraction comma and AB=CD=5 units.
The slope of AB = (4-1)/(5-1)= 3/4
The slope of DC = (0-3)/(6-10) = 3/4
Thus, the two segments have equal slope,
Both segments are also equal in magnitude 5 units
