ABCD is none of the above

Respuesta :

Answer:

  D.  none of the above

Step-by-step explanation:

The sides are different lengths and not at right angles, so the figure is not a rhombus or a rectangle. It is "none of the above."

__

Counting grid squares in the attached figure, we see that one side is the diagonal of a 2×3 rectangle, and the adjacent side is the diagonal of a 1×3 rectangle. This tells you two things: (a) the sides are different length, (b) they are not at right angles to each other. (If the sides were perpendicular, the slopes of the segments would be opposite reciprocals.)
