The figure below shows a parallelogram PQRS.
The flowchart shown below shows the sequence of steps to prove the theorem, “Opposite angles of a parallelogram are equal.”
Which option best represents x and y?
Answer

x = angle 1 is equal to angle 6 and y =corresponding angles

x = angle 5 is equal to angle 3 and y = interior opposite angles

x = angle 4 is equal to angle 3 and y = alternate interior angles

x = Angle 5 is equal to angle 6 and y = supplementary angles

I think it's either the second or 3rd option but from there im stuck help please?

anonymous · Answer

it's the 3rd choice. you can see that the situation for 3rd choice is the same as the one that they given whereby PQ//SR and angle 1 equal to 2.
