To see if the quadrilateral in question is a parrellelogram you have to have to see if it has 2 pairs of parallel sides

How do i prove the sides are parallel

How do i prove the sides are parallel

Well if two lines are cut by a transversal from the 2 sides (in quebec we call it a médiane) then look if the alternate interior angles are congruent after you if the lines are parallel. Also I think you souldve had study the 5 theorems to prove that lines are parallel lol.

If it looks close enough then it is

For all quadrilaterals such that the approximate visual representation of said shape resembles that of a parallelogram, then that shape is a paralologram if and only if it is a paralologram
