In Euclidean geometry, a parallelogram is a (non self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither condition can be proven without appealing to the Euclidean parallel postulate or one of its equivalent formulations. The three-dimensional counterpart of a parallelogram is a parallelepiped. A quadrilateral with one pair of parallel sides is a trapezoid in American English or a trapezium in British English.
The etymology (in Greek παραλληλ-όγραμμον, a shape "of parallel lines") reflects the definition.
Art of Problem Solving's Richard Rusczyk explores the angles of a parallelogram.

How to calculate the area of a parallelogram
People consider parallelograms as the most important type of quadrilateral. Why so? What intriguing properties help define this elusive shape? Watch this video to know more! We at Byju's Classes strongly believe that a spirit of learning and understanding can only be inculcated when the student is curious, and that curiosity can be brought about by creative and effective teaching. It is this approach that makes our lectures so successful and gives our students an edge over their counterparts.

E lascio senza fiato quel filo di speranza
intrisa nella pioggia una foto nella nebbia
chiudersi nel vuoto di un mondo che ancora non c'?
Sono un equilibrista sulla corda del passato
cerco nel presente il sorriso che ho perduto
urtare contro il tempo di un mondo che ancora non c'?
Quante volte impazzirei
quante volte fuggirei
rubando alla luce quello che vorrei
se tornassi indietro io
se trovassi il modo io
per aprire le ali
Ballo su uno specchio
sfiorando quell'immagine che
sento tra le dita
sento vibrare con me
fuori dalle righe non sono pi? fragile
sono quel ricordo che porta
parole e lacrime
parole e lacrime
Se cerco nel cuscino il profumo della vita
seguire ipnotizzato quella linea indefinita
e cadono frammenti di un mondo che ancora non c'?
Planare sulle strade visuute dalla gente
sedurre quel silenzio con un canto provocante
e rido indifferente di un mondo che ancora non c'?
Quante volte impazzirei
quante volte fuggirei
rubando alla luce quello che vorrei
se tornassi indietro io
se trovassi il modo io
per aprire le ali
Ballo su uno specchio
sfiorando quell'immagine che
sento tra le dita
sento vibrare con me
fuori dalle righe non sono pi? fragile
sono quel ricordo che porta
parole e lacrime
parole e lacrime
Strappare dalle labbra pensieri commoventi
cucire con inganni apparenze inesistenti
sbirciare di nascosto quel mondo che ancora non c'?
quel mondo che ancora non c'?
quel mondo che ancora non c'?
