Question

Which of the following is true?

A. Since the slope of AD equals the slope of CB and the slope of DB equals the slope of CA, the
figure is a rectangle.

B. Since both pairs of opposite sides are of equal length, the figure is á square

C. Since AB=CD= 141, the figure is a rectangle.

D. Since AB=CD= 141, the figure is a square.

Answer 1

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

Step-by-step 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.
