Is it a parellelogram?

can you help @freckles?

well find the lengths and see if the opposite lengths are congruent 
if they are then you know it is either parallelogram or a rectangle
if the slopes of the line segments that share a common vertex are opposite reciprocals of one another, then it is a rectangle  
if the slopes of the opposite line segments have the same slope, then is a parallelogram

okay thanks so that means it's a parellelogram, but would that mean the diagonals bisect each other?

i agree with your description of the shape 
yeah opposite line segments are congruent and also same in slope :)

freckles · Answer

by definition they do bisect each other
