Answer: true.
If a quadrilateral is a parallelogram, it has two sets of opposite sides that are congruent. If you follow the picture attacheed, you see that AD equals BC and AB equals DC.
There is a theorem that says that If a quadrilateral is a parallelogram, it has<span> consecutive angles that are supplementary. Suplementary means that, those 2 angles together, form 180º.</span>

Answer:
Step-by-step explanation:
We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.
i.e. the function will become
.
Now, the given function :
Then , after reflection across y axis the new function will become:
