Answer 1

The rectangle is a quadrilateral, specifically a parallelogram, that has two pairs of sides of equal length. In turn, all interior angles are right angles, that is, they measure 90º.

(Choice A)

From the definition we can conclude that the figure described in this option is a rectangle

(Choice B)

Since this figure doesn't have right angles we can conclude it is not a rectangle

(Choice C)

From the definition we can conclude that the figure described in this option is a rectangle
