Respuesta :

Considering the coordinates of the vertices of rectangle ABCD, the appropriate statement that will explain the prove is that of option D. Prove that opposite sides are congruent and the slopes of consecutive sides are opposite reciprocals.

A rectangle is a quadrilateral that has opposite sides to have equal length, and the sum of its interior angles is given as [tex]360^{o}[/tex]. Thus, the coordinates of the given rectangle ensure that the required statement is unique to the rectangle.

Since opposite sides of a rectangle are equal and parallel, then options A and C are wrong. Also, the consecutive sides of the given rectangle do not have the same slope. Thus option B is not appropriate.

But, the inverse and change of the sign of the slope for each consecutive sides gives their opposite reciprocals. Therefore, the statement that is required to prove that quadrilateral ABCD is a rectangle is D.

Option D. Prove that opposite sides are congruent and the slopes of consecutive sides are opposite reciprocals.
