Answer:

C. Since AB = CD = √41, the figure is a rectangle.

Explanation:

All of them AD, CB, DB, CA have a slope of 0.

Here measure the length units, 5 units horizontal and 4 units vertical. Thus we can conclude it is a rectangle.

Find diagonal Length:

  • √(x2-x1)² + (y2-y1)  =  Length from points measure.
  • √(5-0)² + (4-0)²         [insert following coordinates]
  • √25 + 16                   [simplify]
  • √41                           [final answer]

Since AB = CD = √41, the figure is a rectangle.
