If the markings were missing on this quadrilateral, how would you go about verifying what shape it is?
A) Because this is a rectangle, I would show that each vertex is made up with lines that have opposite reciprocal slopes.
B) Because this is a parallelogram, I would show that each vertex is made up with lines that have opposite reciprocal slopes.
C) Because this is a parallelogram, I would show that all four sides are congruent.
D )Because this is a parallelogram, I would show that opposite sides have the same slope.
