The Opposite sides are parallel. ...
Opposite sides are congruent. ...
Opposite angles are congruent. ...
Same-Side interior angles (consecutive angles) are supplementary.
Hence,
By drawing a parallelogram not drawn to scale below, we will have
[tex]\begin{gathered} AB\parallel DC \\ AD\parallel BC \\ AB=DC=1inch \\ AD=BC=2inches \\ \angle ABC=60^0 \\ \angle BCD=120^0 \\ \angle CDA=60^0 \\ \angle DAB=120^0 \end{gathered}[/tex]
